Embodiment Construction

[0025] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0026] like figure 1As shown, the adjustable steering transmission device includes a steering shaft 1, a steering gear 2 and a steering rack 3 for controlling the steering of the wheels. Column one 4, the steering gear 2 is coaxially fixed with transmission column two 5, between transmission column one 4 and transmission column two 5 is provided with a friction disc 6 that can rotate around its own axis, transmission column one 4 and transmission column There is a friction segment 7 with a tapered outer periphery on the second 5. The friction disc 6 can reciprocate along its own axial direction and keep the outer peripheral surface of the friction disc 6 at the same time as the transmission column 4 and the transmission co...

Abstract

The invention provides an adjustable steering transmission device, and belongs to the technical field of steering systems. The technical problem that an existing steering transmission device is fixedin transmission ratio or has potential safety hazards is solved. The adjustable steering transmission device comprises a steering shaft, a steering gear and a steering rack used for controlling steering of wheels, and further comprises a first transmission column in transmission connection with the steering shaft, a second transmission column is coaxially and fixedly arranged on the steering gear,and a friction disc capable of rotating around the axis of the friction disc is arranged between the first transmission column and the second transmission column. The first transmission column and/orthe second transmission column are/is provided with friction sections/a friction section with the periphery in a conical surface shape, and the friction disc can reciprocate in the axial direction ofthe friction disc and always keeps the peripheral surface of the friction disc in friction transmission with the first transmission column and the second transmission column at the same time. The adjustable steering transmission device can achieve stable and smooth adjustment of the transmission ratio of the steering device.

Description

technical field [0001] The invention belongs to the technical field of steering systems, and relates to an adjustable steering transmission device. Background technique [0002] With the development of automobile technology, the safety and stability of automobiles are becoming more and more important, and the steering system, which controls the direction of automobile travel, is particularly important to the safety of automobile driving. In actual driving, we expect the steering system of the car to have a small steering ratio input at low speeds and a large steering ratio input at high speeds in order to maintain straight-line driving performance. However, as a conventional steering system of a traditional car, the ratio of the steering wheel to the steering angle of the front wheels is always constant no matter whether the car is running at a low speed or at a high speed. Compared with the conventional steering system, the variable transmission ratio steering system has a...
