Embodiment Construction

[0024] Such as figure 1 Shown and combined Figure 2~6 As shown, the group steering system of the present invention includes a front steering axle group and a rear steering axle group.

[0025] The front steering axle assembly includes a front axle assembly and a single-circuit steering gear 1 fixed on the frame 2. The single-circuit steering gear 1 is mounted on a steering gear bracket, and the steering gear bracket is fixedly arranged on the frame 2.

[0026] The output shaft of the single-circuit steering gear 1 is fixedly connected with a steering rocker arm 3 through a spline to ensure that the output angle of the single-circuit steering gear 1 and the steering rocker arm 3 can correspond one-to-one. At the same time, the steering distribution valve is integrated in the single-circuit steering gear 1 and is an important component of the steering hydraulic system. The other end of the steering rocker arm 3 is hinged with a front straight rod 4, the other end of the front strai...

Abstract

The invention provides a grouped steering system and relates to a system arranged on a chassis of a vehicle and enabling the vehicle to steer. The invention aims to provide the grouped steering system. The grouped steering system has high safety and high reliability, enables steering wheels to have a coordinated and correct corner relationship, improves the operating stability when the vehicle drives and meets the driving requirements on related roads. The grouped steering system provided by the invention comprises a front steering axle group and a rear steering axle group, wherein the front steering axle group comprises a front axle group and a single-loop steering gear (1) fixed on a vehicle frame (2); an output shaft of the single-loop steering gear is fixedly connected with a steering rocker arm (3); the other end of the steering rocker arm is hinged to a front straight pull rod (4); the other end of the front straight pull rod is hinged to one end of a front swing arm (5); the other end of the front swing arm is hinged to a rear straight pull rod (6); the rear steering axle group comprises a rear axle group and a rotary storage type servo mechanism (17); and the rotary storage type servo mechanism is hinged to a feedback pull rod (18).

Description

Technical field [0001] The invention relates to the field of vehicle chassis, in particular to a system for steering a vehicle installed on the vehicle chassis. Background technique [0002] Due to the characteristics of heavy load and long wheelbase of heavy-duty multi-axle special vehicles, the steering system generally adopts multi-axle group steering system. With the continuous improvement of driving speed, the handling and stability of vehicles has received increasing attention. When the vehicle is turning, all wheels should rotate at the turning center instantaneously, and any wheel should not skid. At the same time, the additional turning angle caused by wheel bounce should be minimized. However, the existing steering system still cannot meet the requirements for safety and stability of vehicle driving. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a grouped steering system with high safety and high reliability...
