Abstract

The invention discloses a special truck chassis for all-wheel drive and full-steering, which is characterized by comprising three major systems: 1. a special truck chassis including a chassis driving system, a power system, a steering system, a suspension system and a frame; 2. Rear axle steering hydraulic control system; 3. Rear axle steering electrical control system. The invention provides a special truck chassis with all front and rear axles driven, the front axle can be steered, and the rear axle can be selected to be steered or not. The special truck chassis can realize three steering functions: front axle steering; Turning radius; rear axle crab steering, the vehicle can achieve oblique translation, increase the motion trajectory of ordinary vehicles, and improve the vehicle position adjustment function.

Description

Technical field [0001] The present invention relates to an all-drive full-turn special truck chassis, belonging to the field of special vehicle, truck technology. Background [0002] The traditional truck chassis steering is steered by the front axle, the rear axle generally has no steering system, in order to improve the vehicle turning performance, increase the vehicle movement trajectory, the need for the rear axle to have a steering function. At present, the main ones visible in China are the spring-loaded servo steering device installed on the rear axle of the passenger car chassis, which is a passive steering servo system, mainly used for three-axle axles, and can reduce the sliding friction with the ground when the tire is steered and the tire wear is reduced after the follow-up function is installed. At present, there are four-wheel full-drive forward steering chassis on the market, but there are no full-drive, full-turn chassis. This patent belongs to the design of a ne...
