Abstract

The invention discloses a wheel-side speed-reducing steering device for mechanical transmission for automobile front and rear axles. The wheel-side speed-reducing steering device comprises a housing,wherein a wheel-side input shaft, a cylindrical external meshing gear pair and a brake, the wheel-side input shaft is connected with a transmission transfer case, the transmission transfer case drivesthe wheel-side input shaft through a main speed reducer to transmit driving torque to a front (or rear) wheel axle through the cylindrical external meshing gear pair, and wheel driving is achieved. The front axle wheel-side speed-reducing steering device can achieve wheel steering under the driving of a steering pull arm through upper and lower main pin seat sphere hinges of a wheel-side housing.The wheel-side speed-reducing steering device can transmit the torque transmitted by the main speed reducer of a front (or rear) axle to a front (or rear) and left (or right) driving wheels in set proportion, so that front wheel steering and driving under the driving of a steering mechanism are achieved. The wheel-side speed-reducing steering device is simple in structure, compact in arrangement,small in occupied space, high in efficiency and accurate and reliable in transmission.

Description

technical field [0001] The invention relates to an automobile steering device, in particular to a wheel-side deceleration steering device for mechanical transmission of the front and rear axles of the automobile, which is used for the front, rear and middle axles of off-road vehicles. Background technique [0002] Modern automobiles often use integral axles or independent suspension axles, which transmit the drive torque directly to the drive wheels through half shafts or drive shafts. The power input center is concentric with the wheel, and the way of increasing the angle between the wheel or the transmission shaft and the wheel axis is often used to improve the passability and maneuverability of the vehicle. However, the effect of the above method is limited. If the tire is too large, it will affect the performance of other parameters of the vehicle, and if the included angle of the initial transmission shaft is too large, it will affect the transmission efficiency of the ...
