Abstract

The utility model relates to a telescopic universal joint of an all-terrain four-wheel recreational vehicle, which comprises a universal connecting tube, and a universal connecting rod, a spring piece and two universal connectors. The two universal connectors are arranged respectively at one end of the universal connecting tube and one end of the universal connecting rod, the other end of the universal connecting tube is inserted into the other end of the universal connecting rod. The spring piece is positioned between the inner spring slot of the universal connecting rod and the inner wall of the universal connecting tube. The telescopic universal joint can automatically stretch out and draw back following angle changes of a steering wheel, and the universal connectors are forced evenly, the adjustable axial clearance of the steering wheel is not reserved, thereby improving comfortableness of the vehicle control and driving safety of drivers.

Description

The universal slip joint of type four-wheel recreational vehicle entirely

Technical field

The utility model relates to vehicle directional systems technology field, especially a kind of universal slip joint of the four-wheel of type entirely recreational vehicle.

Background technology

Type four-wheel recreational vehicle is come from American-European countries entirely, grows up strong and sturdy the fashionable now whole world in China.It adopts the vehicle frame of steel-tube construction, loads onto miniature gasoline engine, and its simple in structure, small and exquisite, light and beautiful are particularly suitable for the sandy beach and path rugged, that jolt travels, the young consumers favor of extremely being keen on sports.Because type four-wheel recreational vehicle vehicle body is less entirely, be subjected to the qualification of locus, the deflector input shaft that the full ground type four-wheel recreational vehicle of prior art is used is positioned at the central authorities of vehicle body, bearing circle is positioned at the left side of vehicle body, the output shaft of deflector input shaft and bearing circle is not on same axis, and what be provided with between the output shaft of deflector input shaft and bearing circle is the fixing universal-joint of axial spacing, kill for preventing to turn to, must be at bearing circle axially leave the adjusting play, when steering wheel rotation, with the variation of corner, the friction force that acts on the Hooke's coupling is not quite similar, when making the steer direction dish, feel neglect indiscreet and negligent heavy, axially shake is made troubles to pilot control, and is had safe driving hidden danger.

The utility model content

The purpose of this utility model is the universal slip joint of a kind of four-wheel of type entirely recreational vehicle of providing at the deficiencies in the prior art, variation with steering wheel angle, universal-joint can stretch voluntarily, Hooke's coupling is stressed evenly, bearing circle axially do not stay the adjusting play, improved chaufeur to the traveling comfort of vehicle performance and the safety of travelling.

The concrete technical scheme that realizes the utility model purpose is:

A kind of universal slip joint of the four-wheel of type entirely recreational vehicle, its characteristics comprise universal connection pipe, universal pipe link, spring leaf and Hooke's coupling, described universal connection pipe is that hollow rectangular tube constitutes by the cross section, universal pipe link is that solid rectangular shaft constitutes by the cross section, and the one side is provided with spring groove vertically; Described Hooke's coupling is two, is located at an end of universal connection pipe and an end of universal pipe link respectively, and the other end of universal pipe link inserts the other end of universal connection pipe, and spring leaf is located in the spring groove of universal pipe link and between the inwall of universal connection pipe.

The utility model can be with the variation of steering wheel angle, and universal-joint can stretch voluntarily, and Hooke's coupling is stressed evenly, bearing circle axially do not stay the adjusting play, improved chaufeur to the traveling comfort of vehicle performance and the safety of travelling.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the local enlarged diagram in Figure 1A-A cross section.

The specific embodiment

Consult Fig. 1, Fig. 2, the utility model comprises universal connection pipe 1, universal pipe link 2, spring leaf 3 and Hooke's coupling 4, described universal connection pipe 1 is that hollow rectangular tube constitutes by the cross section, and universal pipe link 2 is that solid rectangular shaft constitutes by the cross section, and the one side is provided with spring groove 21 vertically; Described Hooke's coupling 4 is two, be located at an end of universal connection pipe 1 and an end of universal pipe link 2 respectively, the other end of universal pipe link 2 inserts the other end of universal connection pipe 1, and spring leaf 3 is located in the spring groove 21 of universal pipe link 2 and between the inwall of universal connection pipe 1.

The utility model is to use like this:

Consult Fig. 1, Fig. 2, the utility model Hooke's coupling 4 one ends are connected with the deflector input shaft, the other end is connected with the output shaft of bearing circle, during Vehicular turn, because Hooke's coupling 4 is located at an end of universal connection pipe 1 and an end of universal pipe link 2 respectively, the other end of universal pipe link 2 is inserted by the other end of universal connection pipe 1, variation with steering wheel angle, universal pipe link 2 can stretch in universal connection pipe 1 voluntarily, a Hooke's coupling transfer torque and do not bear axial force, bearing circle axially also needn't stay the adjusting play, improved chaufeur to the traveling comfort of vehicle performance and the safety of travelling.

Consult Fig. 2, the utility model is provided with spring leaf 3 in the spring groove 21 of universal pipe link 2 and between the inwall of universal connection pipe 1, is used to eliminate the steering gap that contact gap between the universal pipe link 2 universal connection pipes 1 promptly reduces bearing circle.
