Description

Technical Field

[0001] This invention relates to the field of three-wheeled motorcycle technology, and more particularly to a three-wheeled vehicle. Background Technology

[0002] As the market demands higher power performance from three-wheeled motorcycles, some scenarios require the adaptation and installation of automotive four-cylinder powertrains and transmission assemblies onto three-wheeled motorcycles to meet the demand for high-power performance in complex working conditions such as heavy loads, hill climbing, and long-distance travel.

[0003] However, most existing three-wheeled motorcycles use small-displacement powertrains and matching gearboxes, and their clutch operation mostly adopts a direct cable transmission method, mainly relying on the driver to manually control the cable to drive the clutch. This structure is simple and low-cost, but the transmission ratio is fixed and there is no power assist structure, so it can only be used with small-displacement powertrains with low clutch operation resistance.

[0004] Because the clutch operating resistance of an automobile powertrain is much greater than that of a traditional small-displacement powertrain, if the existing cable-operated control mechanism is directly applied to a three-wheeled motorcycle adapted to a four-cylinder automobile powertrain and transmission, it will result in difficult clutch operation, difficulty in achieving smooth control, and easy driver fatigue, which seriously limits the effective application of automobile powertrains in three-wheeled motorcycles. Summary of the Invention

[0005] The purpose of this invention is to provide a tricycle that solves the problem that applying the existing cable-operated control mechanism to a tricycle that is adapted to a four-cylinder powertrain and gearbox of a car results in difficult clutch operation, difficulty in achieving smooth control, and easy driver fatigue, which seriously limits the effective application of the car powertrain in tricycles.

[0006] To achieve the above objectives, the present invention provides a tricycle, which includes a frame, a body, a front end, a powertrain, and a clutch control mechanism. The body is located at the front end of the frame, the front end is located at the front end of the body, a clutch control handle is located on the front end, and the powertrain is mounted on the bottom of the frame.

The control seat is rotatably connected to the control linkage and located at the top of the control linkage. The cable is connected to the control seat, passes through the limit seat, and is connected to the clutch operating handle. One end of the connector is connected to the input end of the first vacuum booster canister, and the other end of the connector is connected to the actuating end of the clutch in the powertrain.

[0007] The clutch operating mechanism further includes a transmission seat and a control lever. The transmission seat is rotatably connected to the control linkage and is located at the bottom of the control linkage. One end of the control lever is connected to the transmission seat, and the other end of the control lever is connected to the first vacuum booster tank.

[0008] The connector includes a sealing seat and a dust cover. The sealing seat is connected to the first vacuum booster tank and is located at the output end of the first vacuum booster tank. The dust cover is fixedly connected to the sealing seat and is located outside the sealing seat.

[0009] The connector further includes an output rod, a connecting rod, and an output link. The output rod is connected to the first vacuum booster tank and passes through the sealing seat and the dust cover. The connecting rod is connected to the power assembly and passes through the power assembly. One end of the output link is rotatably connected to the output rod, and the other end of the output link is fixedly connected to the connecting rod.

[0010] The tricycle also includes an auxiliary cooling device, which comprises a crash barrier, an auxiliary water tank, a temperature sensor, and an auxiliary mechanical fan. The crash barrier is fixedly connected to the side of the vehicle frame. The auxiliary water tank is installed inside the crash barrier. The top and bottom of the auxiliary water tank are respectively provided with a water inlet and an outlet. Both the water inlet and the outlet are connected to the original cooling system of the powertrain through pipes. The temperature sensor is also installed on the auxiliary water tank, with the detection end of the temperature sensor located inside the auxiliary water tank. The auxiliary mechanical fan is fixedly installed on the back of the auxiliary water tank and is electrically connected to the temperature sensor.

[0011] The auxiliary heat dissipation device also includes an overflow water tank, which is installed on one side of the anti-collision frame. The overflow water tank has an interface that is connected to the expansion pipe of the original water cooling system of the powertrain.

[0012] The tricycle also includes a braking mechanism, which comprises a brake pedal, a rotating rod, a pull rod, a rotating arm, and a second vacuum booster. The brake pedal is located at the right foot position at the front of the frame. The brake pedal is rotatably mounted on the frame via the rotating rod, which is rotatably connected to the frame.

The clutch control mechanism includes a support frame, a first vacuum booster, a limiting seat, a control shaft, a control linkage, a control seat, a cable, and a connector. When the driver engages the clutch lever on the front end, the cable drives the control seat and the control linkage to rotate around the control shaft, thereby triggering the first vacuum booster via the connector. The first vacuum booster drives the connector to move, transmitting force to the clutch actuator of the powertrain, thus significantly reducing the pulling force required for clutch operation. This structure transforms the previously laborious and cumbersome pure cable drive into a lightweight, vacuum-assisted control system. The driver only needs to apply a small amount of pulling force to smoothly engage and disengage the clutch, effectively solving the problem of laborious and difficult-to-smooth clutch operation when adapting a four-cylinder automotive powertrain to a tricycle.

Detailed Implementation

[0025] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] Please see Figures 1 to 8 The present invention provides a tricycle, the tricycle including a frame 101, a body 102, a front end 103, a powertrain 104 and a clutch control mechanism. The body 102 is provided at the front end of the frame 101, the front end 103 is provided at the front end of the body 102, and a clutch operation handle 105 is provided on the front end 103. The powertrain 104 is installed at the bottom of the frame 101. The clutch operating mechanism includes a support frame 106, a first vacuum booster tank 107, a limiting seat 108, a control shaft 109, a control linkage 110, a control base 111, a pull cable 112, and connecting parts. The support frame 106 is installed at the bottom of the vehicle frame 101. The first vacuum booster tank 107 is bolted to the support frame 106 and is located on the outside of the powertrain 104. The limiting seat 108 is fixedly connected to the first vacuum booster tank 107 and is located on the outside of the first vacuum booster tank 107. The control shaft 109 is connected to the limiting seat 108. The control linkage 110 is rotatably connected to the control shaft 109 and passes through the limit seat 108. The control seat 111 is rotatably connected to the control linkage 110 and is located at the top of the control linkage 110. The pull cable 112 is connected to the control seat 111, passes through the limit seat 108, and is connected to the clutch operation handle 105. One end of the connector is connected to the input end of the first vacuum booster tank 107, and the other end of the connector is connected to the actuation end of the clutch in the powertrain 104.

[0027] In this embodiment, when the driver squeezes the clutch operating handle 105 on the front of the vehicle 103, the pull cable 112 drives the control seat 111 and the control linkage 110 to rotate around the control shaft 109, thereby triggering the first vacuum booster can 107 through the connector. The first vacuum booster can 107 drives the connector to move, thereby transmitting force to the clutch actuator of the powertrain 104, thus significantly reducing the pulling force required for clutch operation. This structure transforms the originally laborious and cumbersome pure cable 112 transmission into a convenient vacuum-assisted control, allowing the driver to smoothly complete clutch engagement and disengagement with only a small pulling force, effectively solving the problem of laborious and difficult-to-smooth clutch operation after adapting the four-cylinder powertrain 104 of a car to a three-wheeled vehicle.

[0028] Furthermore, the clutch operating mechanism also includes a transmission seat 113 and a control lever 114. The transmission seat 113 is rotatably connected to the control link 110 and is located at the bottom of the control link 110. One end of the control lever 114 is connected to the transmission seat 113, and the other end of the control lever 114 is connected to the first vacuum booster tank 107.

[0029] In this embodiment, when the driver squeezes the clutch operating handle 105, the pull cable 112 drives the control linkage 110 to rotate around the control shaft 109. The bottom of the control linkage 110 pushes the transmission seat 113 to move, and the transmission seat 113 drives the control rod 114 to move, so that the first vacuum booster can 107 generates an assisting effect, thereby amplifying the clutch operating force and reducing the squeezing force required by the driver.

[0030] Furthermore, the connector includes a sealing seat 115, a dust cover 116, an output rod 117, a connecting rod 118, and an output connecting rod 119. The sealing seat 115 is connected to the first vacuum booster tank 107 and is located at the output end of the first vacuum booster tank 107. The dust cover 116 is fixedly connected to the sealing seat 115 and is located outside the sealing seat 115. The output rod 117 is connected to the first vacuum booster tank 107 and passes through the sealing seat 115 and the dust cover 116. The connecting rod 118 is connected to the power assembly 104 and passes through the power assembly 104. One end of the output connecting rod 119 is rotatably connected to the output rod 117, and the other end of the output connecting rod 119 is fixedly connected to the connecting rod 118.

[0031] In this embodiment, the sealing seat 115 is used to seal the gap between the output end of the first vacuum booster tank 107 and the connector, preventing internal pressure leakage of the first vacuum booster tank 107 and ensuring the stability of the boosting effect. The dust cover 116 is made of flexible rubber and is fitted over the outside of the output rod 117. One end of the dust cover is fixedly connected to the sealing seat 115, and the other end can deform with the extension and retraction of the output rod 117 to avoid sealing failure or jamming of the output rod 117.

[0032] Furthermore, the tricycle also includes an auxiliary cooling device, which includes a crash shield 120, an auxiliary water tank 121, a temperature sensor 122, and an auxiliary mechanical fan 123. The crash shield 120 is fixedly connected to the side of the frame 101. The auxiliary water tank 121 is installed inside the crash shield 120. The top and bottom of the auxiliary water tank 121 are respectively provided with an inlet 124 and an outlet 125. The inlet 124 and the outlet 125 are both connected to the original cooling system of the powertrain 104 through pipes. The temperature sensor 122 is also provided on the auxiliary water tank 121. The detection end of the temperature sensor 122 is located inside the auxiliary water tank 121. The auxiliary mechanical fan 123 is fixedly installed on the back of the auxiliary water tank 121 and is electrically connected to the temperature sensor 122.

[0033] In this embodiment, when the original water-cooling system of the powertrain 104 is insufficient in heat dissipation under heavy load or low-speed, high-load conditions, the coolant temperature gradually rises and flows through the auxiliary water tank 121. The temperature sensor 122 monitors the water temperature in real time. When the water temperature is detected to be higher than a preset threshold, the auxiliary mechanical fan 123 is automatically triggered to start and run, forcibly cooling the coolant inside the auxiliary water tank 121. The cooled liquid flows back to the original cooling system of the powertrain 104 through the outlet 125 and the pipe, forming a circulating auxiliary heat dissipation, effectively preventing the engine water temperature of the powertrain 104 from becoming too high.

[0034] Furthermore, the auxiliary heat dissipation device also includes an overflow water tank 126, which is installed on one side of the anti-collision frame 120. The overflow water tank 126 is provided with an interface 127, which is connected to the expansion pipe of the original water cooling system of the powertrain 104.

[0035] In this embodiment, the overflow tank 126 is made of transparent plastic. When the coolant expands due to heat, the excess coolant flows into the overflow tank 126 through the expansion pipe for temporary storage. When the internal pressure of the cooling system decreases or the coolant is insufficient, the coolant in the overflow tank 126 can automatically flow back to replenish it, thereby maintaining the liquid balance of the entire cooling system and preventing coolant loss that would lead to a decrease in heat dissipation capacity.

[0036] Furthermore, the tricycle also includes a braking mechanism, which includes a brake pedal 128, a rotating rod 129, a pull rod 130, a rotating rod 131, and a second vacuum booster 132. The brake pedal 128 is located at the right foot of the front end of the frame 101. The brake pedal 128 is rotatably mounted on the frame 101 via the rotating rod 129. The rotating rod 129 is rotatably connected to the frame 101. A first transmission rod 133 is fixedly mounted on the rotating rod 129. The end of the first transmission rod 133 away from the rotating rod 129 is rotatably connected to the... A pull rod 130 is provided, with a second transmission rod 134 rotatably mounted at one end of the pull rod 130 away from the first transmission rod 133. A rotating rod 131 is fixedly mounted on the second transmission rod 134 and is rotatably connected to the frame 101. A third transmission rod 135 is fixedly mounted at one end of the rotating rod 131 away from the second transmission rod 134. A second vacuum booster tank 132 is fixedly mounted on the frame 101, and the end of the third transmission rod 135 away from the rotating rod 131 is connected to the input end of the second vacuum booster tank 132.

[0037] In this embodiment, the brake pedal 128 is positioned at the driver's right foot, conforming to ergonomic design. When the driver depresses the brake pedal 128, the brake pedal 128 drives the rotating rod 129 to rotate. The first transmission rod 133 on the rotating rod 129 then swings and pulls the pull rod 130. The pull rod 130 drives the second transmission rod 134 and the rotating rod 131 to rotate. The rotating rod 131 then drives the third transmission rod 135 to push the input end of the second vacuum booster can 132. The second vacuum booster can 132 amplifies the braking force using vacuum boosting and transmits it to the brake master assembly. The brake master assembly then transmits the brake fluid from the brake fluid reservoir to the rear axle brake master assembly, ultimately achieving an easy and effortless braking effect.

[0038] Furthermore, the two ends of the pull rod 130 are rotatably connected to the first transmission rod 133 and the second transmission rod 134 respectively via hinge shafts. The first transmission rod 133 is arranged perpendicularly to the rotating rod 129, the second transmission rod 134 is arranged perpendicularly to the rotating rod 131, and the third transmission rod 135 is arranged perpendicularly to the rotating rod 131.

[0039] In this embodiment, the hinged shaft connection ensures flexible rotation between the transmission rods, avoiding motion interference. The arrangement of the first transmission rod 133 perpendicular to the rotating rod 129, the second transmission rod 134 perpendicular to the rotating rod 131, and the third transmission rod 135 perpendicular to the rotating rod 131 allows for smooth directional conversion of the pedaling force in each transmission stage.

[0040] Furthermore, a friction pad 136 is fixedly provided on the upper surface of the brake pedal 128. The friction pad 136 is made of rubber and has anti-slip texture on its surface.

[0041] In this embodiment, the friction pad 136 is fixed to the upper surface of the brake pedal 128 by vulcanization or bonding. The rubber material has good elasticity and wear resistance, which can increase the friction between the driver's shoe sole and the brake pedal 128. The anti-slip pattern adopts a diamond or wave-shaped design, which effectively prevents slipping when stepping on the brake pedal in rainy weather or when the soles of the shoes are wet, thus improving driving safety.

[0042] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
