Abstract

The invention is a multi-degree-of-freedom traction device, which comprises a casing (2), a traction hook (3), a telescopic control device (6) and a swing limiting device (1). The two bushings in the middle of the casing (2) are respectively set on the bosses of the two supports (5) on the upper and lower frames of the vehicle frame (10); the traction shaft of the traction hook (3) passes through the (2) the inner cylinder of the front collar (4), the damping spring (9) and the rear collar (17) of the telescopic control device (6) in the cavity; the pull rod (11) passes through the The lug and the skirt are connected to one end of the "Z" shaped lever (13) through the pin shaft and the earring (12); the swing limiter (1) is fixed on the vehicle frame (10) through the positioning pin support (25) , and make the lower end of the positioning pin (27) drop into the positioning groove of the casing (2). The invention realizes multi-degree-of-freedom traction through the telescopic control device (6) and the swing limit device (1), so that the car can be quickly articulated without multiple carriage returns when articulated with the towed equipment.

Description

Multi-degree-of-freedom traction device 1. Technical field [0001] The present invention relates to vehicle traction, in particular to a multi-degree-of-freedom traction device. 2. Background technology Most of the traction devices currently used in vehicles are single degrees of freedom, that is, the main shaft of the traction hook passes through the shell of the traction device, A gap fit is formed between the two; a slotted nut is installed at the tail of the main shaft of the towing hook to limit the free movement of the towing hook in the axial direction; The shell is fixed on the vehicle frame by bolts, so that the tow hook can only rotate around the axis of the tow hook. In this way, the car is hooked to the traction equipment When the vehicle cannot return to the proper position, it is difficult to hang the traction hook on the traction equipment. Time consuming. 3. Contents of the invention In order to overcome existing in the prior art, need repeated carr...
