Description

Technical Field

[0001] The invention relates to a brake assembly of a vehicle, in particular to a linked brake device of a three-wheel vehicle. Background Art

[0002] See also Figure 1 , is a conventional linked brake system 1, which comprises two front brake assemblies 11 for two front wheels (not shown in the figure), a rear brake assembly 12 for a rear wheel (not shown in the figure), a diverter valve 13 connected to the front brake assemblies 11 and the rear brake assembly 12 and used for conveying hydraulic oil, a foot brake pump 14 connected to the diverter valve 13 and the rear brake assembly 12, a rear brake handle 15 connected to the foot brake pump 14 and used for operating the rear brake assembly 12, and a front brake handle 16 connected to the diverter valve 13 and used for operating the front brake assemblies 11. The diverter valve 13 controls the diversion of hydraulic oil, so that the operation of the foot brake pump 14 can simultaneously control the front brake assemblies 11 and the rear brake assembly 12, thereby simultaneously generating a linked braking effect on the front wheels and the rear wheels.

[0003] In order to simplify the configuration of the overall hydraulic oil pipeline under the premise of achieving the front wheel and the rear wheel linkage brake, the rear brake handle 15 is directly connected to the pedal brake pump 14, and the front brake handle 16 is also connected to the diverter valve 13 together with the pedal brake pump 14. Therefore, if the rider only operates the rear brake handle 15 to produce a simple braking effect on the rear wheel, the hydraulic oil will first pass through the pedal brake pump 14 before being transmitted to the rear brake assembly 12, thereby affecting the original normal operation of the pedal brake pump 14 during the process; and when only operating the front brake handle 16, although the front brake assemblies 11 can be operated at the same time by the diversion of the diverter valve 13, the hydraulic oil will be introduced into the diverter valve 13, which will inevitably affect the operation of the pedal brake pump 14 during the process.

[0004] In addition, for the operation of simultaneously braking the front wheel and the rear wheel which is used more frequently when riding, in addition to the operation of only stepping on the foot brake pump 14 which is relatively unintuitive for the rider, if the more intuitive operation of pressing the rear brake handle 15 and the front brake handle 16 at the same time is performed, the operation of the rear brake handle 15 will cause a portion of the hydraulic oil to flow back to the diverter valve 13 after being introduced into the foot brake pump 14, thereby interfering with the flow direction of the hydraulic oil flowing into the diverter valve 13 when the front brake handle 16 is pressed at the same time, thereby causing interference with the mutual operation between the rear brake handle 15 and the front brake handle 16. Summary of the invention

[0005] [Problems to be Solved by the Invention]

[0006] Therefore, an object of the present invention is to provide a linkage brake device for a three-wheeled vehicle that can provide multiple brake modes for the three-wheeled vehicle and prevent the more commonly used brake modes from being disturbed during operation.

[0007] [Technical means to solve the problem]

[0008] Therefore, the linked brake device of the three-wheeled vehicle of the present invention comprises a front wheel and two rear wheels. The linked brake device of the three-wheeled vehicle comprises a front brake unit which is suitable for being arranged on the front wheel and defines a first flow channel and a second flow channel which are independent of each other and suitable for introducing a hydraulic oil, a rear brake unit which is suitable for being arranged on the rear wheels and defines two inner flow channels which are suitable for introducing the hydraulic oil, a front operating mechanism connected to the front brake unit, a control valve which is connected to the second flow channel of the front brake unit and the inner flow channels of the rear brake unit, a rear operating mechanism connected to the control valve, and a pedal mechanism connected to the control valve.

[0009] The front operating mechanism comprises a front brake pump connected to the first flow channel of the front caliper, and a front pull rod connected to the front brake pump and used for operating the front brake unit to produce a braking effect on the front wheel.

[0010] The rear operating mechanism comprises a rear brake pump connected to the inner flow channels of the rear brake unit, and a rear pull rod connected to the rear brake pump and used for operating the rear brake unit to produce a braking effect on the rear wheels.

[0011] The pedal mechanism includes a foot brake master cylinder connected to the control valve, and a pedal rod connected to the foot brake master cylinder and used to operate the front brake unit and the rear brake unit to simultaneously produce a braking effect on the front wheel and the rear wheels.

[0012] In some embodiments of the present invention, the front brake unit includes a front caliper, which includes a main body and three cylinder bodies arranged on the main body, and the first flow channel is connected to two of the cylinder bodies, and the second flow channel is connected to the other cylinder body.

[0013] In some embodiments of the present invention, the front brake unit includes two front calipers, each of which includes a body portion and at least one cylinder portion disposed on the body portion. The first flow channel is connected to the at least one cylinder portion of one of the front calipers, and the second flow channel is connected to the at least one cylinder portion of the other front caliper.

[0014] In some embodiments of the present invention, the foot brake master cylinder of the pedal mechanism is connected to the second flow channel of the front brake unit.

[0015] In some embodiments of the present invention, the control valve includes two oil inlet holes respectively connected to the rear brake pump and the foot brake master cylinder and suitable for introducing hydraulic oil, and an oil outlet hole connected to the rear brake unit.

[0017] In some embodiments of the present invention, the three-wheeled vehicle further comprises a head pipe and an inner fender disposed between the head pipe and the front wheel, wherein the control valve is disposed in front of the head pipe and located above the inner fender.

[0018] [Effects that can be achieved by the present invention]

[0019] The linked brake device of the three-wheeled vehicle of the present invention, when the pedal mechanism is arranged in accordance with regulations, since the front operating mechanism is directly connected to the front brake unit, the rider can operate the front pull rod of the front operating mechanism and the rear pull rod of the rear operating mechanism at the same time according to the most intuitive operating habits. The paths of the front brake pump and the rear brake pump for transmitting hydraulic oil will not interfere with each other, thereby providing a variety of braking modes for the three-wheeled vehicle while avoiding interference with the more commonly used braking modes during operation.

[0020] In some embodiments of the present invention, no matter the front brake unit is configured with one front caliper or two front calipers, the flow channel design of the control valve can be coordinated, and the first flow channel and the second flow channel can be independently configured.

[0021] In some embodiments of the present invention, the rear calipers of the rear brake unit can respectively produce braking effects on the rear wheels when actuated, thereby ensuring the reliability and stability of braking.

[0022] In some embodiments of the present invention, considering that the control valve is the center of the hydraulic oil transmission pipeline configuration, the control valve is separated from the head pipe that rotates frequently during riding, which can prevent the configured pipeline from being pulled during riding and make the pipeline configuration smoother.

[0058] See also Figures 2 to 4 , is an embodiment of the linkage brake device of a three-wheeled vehicle of the present invention, the three-wheeled vehicle comprises a front wheel 91, two rear wheels 92, a head pipe 93, and an inner fender 94 disposed between the head pipe 93 and the front wheel 91. The inner fender 94 is as shown in FIG. Figure 4 A longitudinal through hole 940 is formed to allow pipelines for transmitting hydraulic oil to pass through, and when the faucet connected to the head pipe 93 is turned, it will not cause interference with the inner soil remover 94, so that the pipelines can be arranged more smoothly along the longitudinal extension. Figure 5 And cooperate Figure 2 The present embodiment includes a front brake unit 2 which is suitable for being arranged on the front wheel 91 and defines a first flow channel 201 and a second flow channel 202 which are independent of each other and suitable for introducing the hydraulic oil, a rear brake unit 3 which is suitable for being arranged on the rear wheels 92 and defines two inner flow channels 301 which are suitable for introducing the hydraulic oil, a front operating mechanism 4 connected to the front brake unit 2, a control valve 5 which is connected to the second flow channel 202 of the front brake unit 2 and the inner flow channels 301 of the rear brake units 3, a rear operating mechanism 6 connected to the control valve 5, and a pedal mechanism 7 connected to the control valve 5.

[0059] See also Figure 5 And cooperate Figure 3The front brake unit 2 includes a front caliper 21, which includes a main body 211 and three cylinders 212 disposed on the main body 211 and adapted to be operated by hydraulic oil. The first flow channel 201 is connected to two of the cylinders 212, and the second flow channel 202 is connected to another cylinder 212. It should be noted that the first flow channel 201 and the second flow channel 202, in addition to being grooves defined by the internal structure of the main body 211 of the front caliper 21, also constitute a flow path for the hydraulic oil to flow together with the connected pipelines (see FIG. 2 ). Figure 5 In addition, the rear brake unit 3 includes two rear calipers 31 corresponding to the rear wheels 92, and the inner flow channels 301 of the rear calipers 31 have the same mechanism as the first flow channel 201 and the second flow channel 202, which will not be described in detail later.

[0060] The front operating mechanism 4 includes a front brake pump 41 connected to the first flow channel 201 of the front caliper 21, and a front tie rod 42 connected to the front brake pump 41 and used to operate the front caliper 21 of the front brake unit 2 to produce a braking effect on the front wheel 91. The rear operating mechanism 6 includes a rear brake pump 61 connected to the inner flow channels 301 of the rear brake unit 3, and a rear tie rod 62 connected to the rear brake pump 61 and used to operate the rear calipers 31 of the rear brake unit 3 to produce a braking effect on the rear wheels 92. By means of the front brake pump 41 and the rear brake pump 61, when the front tie rod 42 and the rear tie rod 62 are operated, the hydraulic oil can flow in the first flow channel 201 and the inner flow channels 301 respectively, thereby operating the front caliper 21 and the rear calipers 31 to produce a braking effect.

[0061] The control valve 5 includes two oil inlet holes 501 respectively connected to the rear brake pump 61 and the foot brake master pump 71 and suitable for introducing hydraulic oil, and an oil outlet hole 502 connected to the rear brake unit 3. Considering that the control valve 5 is the center of the transmission pipeline configuration of the hydraulic oil, the control valve 5 is configured in front of the head pipe 93 and above the inner fender 94, so as to cooperate with the configuration that the front operating mechanism 4, the rear operating mechanism 6, and the front brake unit 2 are generally located at a relatively forward position of the three-wheeled vehicle, so that the configuration of the pipeline for transmitting hydraulic oil is smoother, and the control valve 5 is separated from the head pipe 93 that rotates frequently during riding, so as to avoid the configured pipeline being pulled during riding. Among them, the control valve 5 mainly outputs the hydraulic oil introduced from the oil inlet holes 501 to the rear calipers 31 from the oil outlet hole 502.

[0062] The pedal mechanism 7 includes a brake master cylinder 71 connected to the control valve 5, and a pedal lever 72 connected to the brake master cylinder 71 and used to operate the front brake unit 2 and the rear brake unit 3 to simultaneously produce a braking effect on the front wheel 91 and the rear wheels 92. Figure 6 As the name implies, the pedal rod 72 is for the rider to step on, thereby causing the foot brake master cylinder 71 connected to the second flow channel 202 to drive the hydraulic oil in the corresponding pipeline, so that the hydraulic oil flows to the second flow channel 202 and the control valve 5. At this time, the hydraulic oil through the second flow channel 202 drives the front caliper 21 to operate, and the hydraulic oil flowing to the rear calipers 31 through the control valve 5 drives the rear calipers 31 in a different flow path from that flowing to the front caliper 21, thereby producing a braking effect on the front wheel 91 and the rear wheels 92 at the same time.

[0063] See also Figure 5 and Figure 6 In this embodiment, the front rod 42, the rear rod 62, and the pedal rod 72 can be operated individually or in combination in different arrangements, so that three braking modes of each operating individually, three braking modes of two of the three operating simultaneously, and seven braking modes of the front rod 42, the rear rod 62, and the pedal rod 72 operating simultaneously can be generated. Among the seven braking modes, the most intuitive and most commonly used mode for the rider is the mode of pulling the front rod 42 and the rear rod 62 at the same time. In the case of operating the front rod 42 and the rear rod 62 at the same time, since the hydraulic oil drives the front caliper 21 through the first flow channel 201 and drives the rear calipers 31 through the control valve 5, respectively, when the flow paths driving the front caliper 21 and the rear calipers 31 are independent, there will be no mutual interference between the two. In this way, the performance of the most commonly used braking mode can be optimized, so that the rider can operate the brake more smoothly.

[0064] It should be particularly noted that when the mode of operating the foot pedal 72 and the front pull rod 42 at the same time is adopted, since the foot brake master cylinder 71 is connected to the second flow channel 202, it is independent of the hydraulic oil path of the front brake pump 41 through the first flow channel 201, and thus will not cause interference; and when the mode of operating the foot pedal 72 and the rear pull rod 62 at the same time is adopted, since the rear brake pump 61 is connected to the control valve 5 but not directly connected to the foot brake master cylinder 71, the mutual interference of the braking effects can be minimized.

[0065] See also Figure 7, which is another implementation of the present embodiment, the front brake unit 2 includes two front calipers 21, each of which includes a body 211 and a cylinder 212 disposed on the body 211. The first flow channel 201 is connected to the cylinder 212 of one of the front calipers 21, and the second flow channel 202 is connected to the cylinder 212 of the other front caliper 21. This implementation achieves the purpose of making the first flow channel 201 and the second flow channel 202 independent of each other by directly disposing two front calipers 21, so that the front pull rod 42 and stepping on the foot lever 72 will respectively operate different front calipers 21 without causing mutual interference. In addition, when the front pull rod 42 and the rear pull rod 62 are operated at the same time, the purpose of non-interference operation can still be achieved.

[0066] In summary, the interlocking brake device of the three-wheeled vehicle of the present invention, when the pedal mechanism 7 is provided in accordance with the regulations, since the front operating mechanism 4 is directly connected to the front brake unit 2, it does not affect the control of the rear operating mechanism 6 to the rear brake unit 3 through the control valve 5. Therefore, when the rider operates the front pull rod 42 and the rear pull rod 62 at the same time according to the most intuitive operating habits, the paths for transmitting hydraulic oil will not interfere with each other, thereby providing multiple braking modes for the three-wheeled vehicle while avoiding interference with the more commonly used braking modes during operation. Therefore, the purpose of the present invention can be achieved.

[0067] The above descriptions are merely embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. All simple equivalent changes and modifications made according to the claims and description of the present invention are still within the scope of the present invention.
