Abstract

The utility model discloses a direction control device for an electric vehicle and relates to a steering device. The direction control device comprises a steering gear, a pull rod, a central rocker arm and steering connecting rods. One end of the steering gear is connected with the pull rod through a fork-shaped joint. The other end of the pull rod is fixed on the central rocker arm through a pin shaft. The steering connecting rods are respectively and symmetrically fixed on the left side and the right side of the central rocker arm. The tail ends of the steering connecting rods are respectively connected with left and right front wheels. The direction control device for the electric vehicle has a simple structure, is convenient to connect and has low influence on the positioning of the front wheels. The wear to tires is reduced. A steering wheel is rotated with less effort.

Description

A kind of electric vehicle directional control device

Technical field

The utility model relates to a kind of steering hardware, specifically a kind of electric vehicle directional control device.

Background technology

Steering hardware is for the turning that realizes automobile is provided with, and is made up of steering box, bearing circle, steering hardware and wheel flutter etc., along with the widespread usage of electronlmobil; Steering hardware on the general-utility car also is applied in the electronlmobil; But, take than large space to a certain extent, and also there is the problem of recoil in common steering hardware owing to the pipe link that the steering hardware on the general-utility car is included is more; Bigger to the influence of vehicle front location; Cause the mill tire easily, lighter weight of electronlmobil own so back attack phenomenon are particularly serious, and terms of settlement is not also arranged at present.

The utility model content

The purpose of the utility model is to provide a kind of electric vehicle directional control device, addresses the above problem.

The utility model solves the technical scheme that its technical matters adopted: a kind of electric vehicle directional control device; It is characterized in that; Comprise deflector, pull bar, central rocking arm and Linkage steering, described deflector one end is connected with pull bar through forked element, and the other end of pull bar is fixed on the central rocking arm through bearing pin; The central authorities rocking arm left and right sides respectively symmetry be fixed with Linkage steering, the end of Linkage steering is connected with left and right sides front vehicle wheel respectively; Described central rocking arm comprises fixed end, first support arm and second support arm; Described fixed end passes through bearing fixing on vehicle frame; The end of first support arm is provided with a through hole; Be connected with pull bar through bearing pin, second support arm terminal symmetrical is provided with two through holes, is connected with Linkage steering through bearing pin respectively.

The beneficial effect of the utility model is: simple in structure, easy to connect, and little to the front wheel alignment influence, reduce the mill tire, steering wheel rotation is more laborsaving.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Among the figure: 1 deflector, 2 pull bars, 3 central rocking arms, 31 fixed ends, 32 first support arms, 33 second support arms, 4 Linkage steerings

The specific embodiment

As shown in Figure 1; A kind of electric vehicle directional control device; Comprise deflector 1, pull bar 2, central rocking arm 3 and Linkage steering 4, described deflector 1 one ends are connected with pull bar 2 through forked element, and the other end of pull bar 2 is fixed on the central rocking arm 3 through bearing pin; Central authorities rocking arm 3 left and right sides respectively symmetry be fixed with Linkage steering 4, the end of Linkage steering 4 is connected with left and right sides front vehicle wheel respectively; Described central rocking arm 3 comprises fixed end 31, first support arm 32 and second support arm 33; Described fixed end 31 passes through bearing fixing on vehicle frame; The end of first support arm 32 is provided with a through hole; Be connected with pull bar 2 through bearing pin, second support arm 33 terminal symmetrical is provided with two through holes, is connected with Linkage steering 4 through bearing pin respectively.

Deflector 1 is connected with bearing circle, and steering wheel rotation drives deflector 1 up-and-down movement, and deflector 1 drives pull bar 2; Pull bar 2 drives 32 rotations of first support arm, and central rocking arm 3 is fixed on the vehicle frame through fixed end 31, and can rotate around vehicle frame; When first support arm, 32 clickwises, second support arm 33 is the while clickwise also, and the Linkage steering 4 that is fixed on second support arm 33 is moved to the left; The drive wheel turns left, and when first support arm, 32 left-hand revolutions, second support arm 33 is the while clickwise also; Drive Linkage steering 4 and move to right, drive wheel simultaneously and turn right.
