Description

Technical Field

[0001] This utility model belongs to the field of vehicle technology, and in particular relates to a height-adjustable vehicle suspension system. Background Technology

[0002] Currently, the vehicle suspension system, as a crucial component of a vehicle, plays a key role in its comfort, handling, and safety. With the development of the automotive industry, user demands for vehicle usage scenarios and functions are becoming increasingly diverse. Different usage scenarios often require wheels of different sizes to meet requirements such as passability and load capacity.

[0003] However, most existing vehicle suspension systems are designed for specific wheel sizes and have relatively fixed structures. If it is necessary to replace wheels of different sizes, multiple components of the suspension system often need to be replaced or modified, which is not only cumbersome, time-consuming, and labor-intensive, but also costly.

The steering knuckle has a first mounting portion and a second mounting portion with different vertical heights. The wheel is connected to either the first or second mounting portion. Two front wheel modules are respectively mounted on opposite sides of the front end of the frame via the steering knuckle. The rear end of the support has a third and a fourth mounting portion with different vertical heights. The rear wheel module is connected to either the third or fourth mounting portion. When the front wheel module is connected to the first mounting portion, the rear wheel module is connected to the third mounting portion; when the front wheel module is connected to the second mounting portion, the rear wheel module is connected to the fourth mounting portion.

The plurality of mounting posts are fixed to the plurality of first mounting holes, so that the shaft core is fixed to the first mounting part; or the plurality of mounting posts are fixed to the plurality of second mounting holes, so that the shaft core is fixed to the second mounting part.

[0011] Furthermore, the vehicle suspension system also includes a buffer module and a drive module. The drive module includes a drive shaft and a drive motor mounted on the drive shaft. The buffer module includes a leaf spring and a second shock absorber. The two ends of the second shock absorber are respectively connected to the leaf spring and the vehicle frame.

[0034] It is understood that the vehicle suspension system provided in this embodiment can be adapted to two different wheel sizes. Without replacing too many parts, the vertical height of the frame 1 from the ground can be adjusted to match the size of the wheel simply by simultaneously adjusting the mounting positions of the front wheel module 2 and the rear wheel module 3 on the frame 1.

[0035] The installation positions of two different sized wheels are explained in detail through two examples.

[0036] Example 1

[0037] Reference Figures 1 to 6 In this embodiment, the front wheel module 2 is connected to the first mounting part 21, and the rear wheel module 3 is connected to the third mounting part 111. This embodiment is suitable for smaller wheels.

[0038] The front wheel module 2 includes a front wheel 23 and a steering knuckle 25. The steering knuckle 25 is provided with a first mounting part 21 and a second mounting part 22 with different vertical heights. The front wheel 23 is connected to the first mounting part 21 through the front wheel hub 24. The steering knuckle 25 is located on both sides of the front end of the frame 1.

[0039] The frame 1 is equipped with a double wishbone independent suspension 13, and the steering knuckle 25 is rotatably connected to the double wishbone independent suspension 13. The steering knuckle 25 can rotate relative to the double wishbone independent suspension 13.

[0040] The steering knuckle 25 includes a base plate 251 and a shaft core 252. A first mounting part 21 and a second mounting part 22 are disposed on the base plate 251.
