Description

Technical Field

[0001] This invention relates to a chassis, specifically to a hybrid electric transport chassis. Background Technology

[0002] Currently, tracked mobile devices are electrically driven, but this single-powered operation results in short continuous working times, reduced efficiency, and extended working hours. Furthermore, existing tracked mobile devices cannot separate the reducer from the wheel hub. When a tracked mobile device needs to carry a load and climb hills and overcome obstacles, it generates very high torque. High torque necessitates the use of a reducer with a high reduction ratio. However, a high reduction ratio means that the reduction gears in the reducer bear significant forces at high speeds, shortening their lifespan. Conversely, a low movement speed inevitably reduces the device's operational efficiency, leading to higher time costs. Summary of the Invention

[0003] The purpose of this invention is to provide a transportation chassis that solves the problems of a single power source and low working efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A transport chassis, comprising: A frame system, the frame system comprising: a mudguard and a housing, the mudguard being connected to the housing via frame welds; The transport vehicle body system is connected to the frame system on both sides, including sliding components.

A tracked suspension system is connected to a frame system for movement of the frame system. The tracked suspension system includes tracks, and within the suspension system are a support roller assembly, a trailing roller assembly, and a tension roller assembly. Shock absorbers are connected to the support roller assembly to reduce the impact during movement. The trailing roller assembly is connected to the frame system and supports the tracks, while the tension roller assembly is connected to the frame system and tensions the tracks to prevent them from becoming loose. A hybrid electric vehicle system, which is fixed within a frame system, includes a range extender, a drive assembly, and a battery. The battery serves as an energy source to power the electrical components, the range extender is used to increase the driving range, and the drive assembly is used to convert electrical energy into mechanical energy to provide power. The cooling and heat dissipation system includes a circulating water pump and a radiator. The radiator is connected to the circulating water pump, and the circulating water pump exchanges heat between the drive components on both sides through the circulating pipeline, thereby cooling the chassis. The electronic control system, fixed to the frame system, includes ultrasonic sensors, an emergency stop button, radar, a pan-tilt unit, an infrared camera, and a GPS antenna. The ultrasonic sensors are used for visible light image recognition, the pan-tilt unit is used for gas concentration detection, the infrared camera is used for infrared thermal imaging temperature measurement, the GPS antenna is used for microphone detection, the radar is used for road condition identification, and the emergency stop button is used to improve production safety.

[0005] Furthermore, the sliding assembly includes a sliding seat weldment and a traction hook. A stud for fixing is connected to the sliding seat weldment, and a washer is provided between the stud and the sliding seat weldment. The traction hook is fixed at both ends of the sliding seat weldment.

[0006] Furthermore, the support roller assembly includes a support roller, a support roller axle weldment, a double-row angular contact ball bearing, and an inner wheel cover; the two support rollers are connected by a first connecting shaft, the support roller axle weldment is fixed on the first connecting shaft, the double-row angular contact ball bearing is connected to both ends of the first connecting shaft, and a bearing baffle is provided on the outer side of the double-row angular contact ball bearing for axial fixation of the double-row angular contact ball bearing; the inner wheel cover is fixed to the support roller by bolts and is located outside the bearing baffle.

[0007] Furthermore, the towing wheel assembly includes a towing wheel shaft weld, a towing wheel, and a deep groove ball bearing; the two towing wheels are connected by a second connecting shaft, the two ends of which are connected to the deep groove ball bearing, and the towing wheel shaft weld is connected to the second connecting shaft.

[0008] Furthermore, the tensioning wheel assembly includes a tensioning welded body, a tensioning slide, a tensioning wheel, and a double-row angular contact ball bearing; the tensioning wheels are connected to each other via a third connecting shaft, with the double-row angular contact ball bearings connected to both ends of the third connecting shaft, and the tensioning slide connected to the third connecting shaft.

[0009] Furthermore, the drive assembly includes a wheel hub, a protective shell, and a shifting device. The wheel hub is bolted to the protective shell, and the wheel hub meshes with the track via a drive shaft located on both sides of the wheel hub. The protective shell has a cavity, and a motor is installed inside the cavity. The movable end of the motor is connected to a reducer, and the output end of the reducer is connected to the shifting device via a transmission component.

[0014] Compared with the prior art, the present invention has the following advantages and beneficial effects: This invention provides power through a hybrid electric system and adds a range extender to extend operating time, thereby shortening the total working time and improving work efficiency. Furthermore, by adding a first and second transmission ring between the reducer and the wheel hub, the reducer provides power to the wheel hub through the second transmission ring. The first and second transmission rings can generate relative displacement. When the first and second transmission rings are engaged, the reducer provides power to the wheel hub through both rings. When the engagement mechanism disengages the first and second transmission rings, the reducer stops providing power to the wheel hub, causing it to rotate passively. The wheel hub then drives the second transmission ring to rotate, and finally, the engagement mechanism releases the rotation of the first transmission ring, achieving high-speed traction of the wheel hub, enabling a wheel hub speed of up to 80 kilometers per hour. This invention, by adding a transmission component between the reducer and the wheel hub, achieves high-speed traction of the wheel hub while protecting the transmission component.

The tension roller assembly 34 is connected to the frame system 1 and tensions the track 31 to prevent it from becoming loose. The track 31 increases the contact area with the ground, reduces the pressure on the ground, and enables stable operation even on soft ground.

[0032] Combination Figure 3 and Figure 4 The support roller assembly 32 includes a support roller 321, a support roller axle weldment 322, a double-row angular contact ball bearing 323, and an inner wheel cover 324. The two support rollers 321 are connected by a first connecting shaft. The support roller axle weldment 322 is fixed to the first connecting shaft 325.

The radiator 45 is connected to the circulating water pump 44, which connects the drive assemblies 42 on both sides through circulation pipes. During operation, components that generate power loss produce heat, which can cause varying degrees of damage. Water cooling is used to cool these components, bringing them to thermal equilibrium. The cooling water exchanged with the components is then used for air cooling, extending the service life of these components. The electronic control system 6 is fixed on the frame system 1 and includes an ultrasonic sensor 61, an emergency stop button 62, a radar 63, a pan-tilt unit 64, an infrared camera 65, and a GPS antenna 66.

[0036] Combination Figure 13 The drive assembly 42 includes a hub 421, a protective shell, and a shifting device. The hub 421 is bolted to the protective shell. The hub 421 meshes with the track 31 via a drive shaft 424, which is located on both sides of the hub 421. The protective shell has a cavity, and a motor 425 is installed inside the cavity. The movable end of the motor 425 is connected to a reducer 426. The output end of the reducer 426 is connected to the shifting device via a transmission component. The transmission component is connected to the hub 421 via an adapter plate 427.

[0037] Combination Figure 14 The transmission component includes a first transmission ring 428 and a second transmission ring 429. The inner and outer sides of the first transmission ring 428 have gear teeth. The output end of the reducer 426 meshes with the inner side of the first transmission ring 428, and the second transmission ring 429 meshes with the outer side of the first transmission ring 428. The second transmission ring 429 is connected to the hub 421 through a fourth connecting shaft.

[0038] The shifting component is connected to the second transmission ring 429 via an end cap. The shifting component includes a shifting shaft 431, a shifting handle 432, and a connecting member 433. The inner side of the connecting member 433 is fixedly connected to the shifting shaft 431 via a thrust ball bearing, and the outer side of the connecting member 433 is fixedly connected to the first transmission ring 428. A gear position sleeve 434 is provided on the end cap, through which the shifting shaft 431 passes and connects to the first transmission ring 428. A return spring 435 is provided on the shifting shaft 431, located between the connecting member 433 and the end cap. The shifting handle 432 is located at one end of the shifting shaft 431, and through the shifting shaft 431, the first transmission ring 428 moves within the end cap, thereby controlling whether the first transmission ring 428 and the second transmission ring 429 are engaged. The gear position sleeve 434 has two pairs of gear position grooves: a first gear position groove 436 and a second gear position groove 437.

[0039] During normal driving, the gear shifter is in the first gear slot 436, the return spring 435 is in its normal state, and the gear shift lever 432 drives the gear shift shaft 431 to produce displacement. The gear shift shaft 431, through the connecting piece 433, engages the inner side of the first transmission ring 428 with the output end of the reducer 426, and the outer side of the first transmission ring 428 is fully engaged with the second transmission ring 429, thereby connecting the reducer 426 to the wheel hub 421 through the second transmission ring 429. When the motor 425 starts, the motor 425 provides power to the reducer 426, and the reducer 426 drives the first transmission ring 428 to rotate through its output end. The first transmission ring 428 causes the second transmission ring 429, which is engaged with it, to rotate, and the second transmission ring 429 causes the wheel hub 421 to rotate through the connecting shaft.

[0040] When being towed, the gear shift lever 432 is in the second gear slot 437, the return spring 435 is compressed, and the gear shift shaft 431, through the connector 433, completely disengages the first transmission ring 428 from the second transmission ring 429. Under towing conditions, the wheel hub 421 rotates passively, driving the second transmission ring 429 to rotate. The second transmission ring 429, through the end cap, causes the gear shift lever 432 and the gear shift shaft 431 to rotate. Ultimately, the gear shift shaft 431 transmits the rotational force to the thrust ball bearing, releasing the rotation of the first transmission ring 428. This achieves the goal of rotating the wheel hub 421, keeping the reducer 426 stationary, and allowing the wheel hub 421 to be towed at high speed.
