Abstract
The utility model discloses a follow-up rear axle for a camper. The follow-up rear axle comprises a rear axle fixing seat (2), a torsion axle (3), a rear wheel axle (7), a torsion axle sleeve (5) and a plurality of rubber sleeve gaskets (6); wherein the rear axle fixing seat (2) is connected with the bottom of a chassis supporting rack (1), the rear wheel axle (7) is connected with the torsion axle (3), the torsion axle sleeve (5) is connected with the rear axle fixing seat (2), the torsion axle (3) and the rubber sleeve gaskets (6) are positioned in the torsion axle sleeve (5), and the rubber sleeve gaskets (6) are covered on the torsion axle (3). The follow-up rear axle has the advantage that the phenomenon of breakage of the torsion axle can be avoided.
Description
Technical field:
The utility model relates to a kind of camping car of pulling on other self-propelled vehicle vehicles, specifically is a kind of camping car servo-actuated back axle.
Background technology:
As everyone knows, can follow self-propelled vehicle to travel together, the servo-actuated back axle that can play the carrying effect all is installed on the car body bracing frame of camping car for the camping car that guarantees to pull on other self-propelled vehicle vehicles.At present, Chang Gui camping car servo-actuated back axle comprises the back axle permanent seat, turns round axle and two hind axles; Described back axle permanent seat is welded on the bottom of car body bracing frame; The described axle of turning round is welded on the back axle permanent seat; Described two hind axles are welded on the two ends of turning round axle respectively; Described hind axle is connected with the bearing that is used for installing trailing wheel usually.There is a defective in actual applications in the camping car servo-actuated back axle of said structure: promptly be uneven when camping car travels, on the rugged open-air ground time, trailing wheel will be subjected to bigger concussion, and the vibratory forces that trailing wheel is subjected to can be directly passed to by hind axle and turns round axle, since described turn round the axle be directly to be welded on to turn round a two ends, therefore, when turning round axle can not in time vibratory forces be passed to the car body bracing frame time, crack conditions will occur, thereby make the camping car can't cruising.
The utility model content:
The technical problems to be solved in the utility model is that a kind of camping car servo-actuated back axle that phenomenon of rupture takes place axle that can prevent to turn round is provided.
Technical solution of the present utility model is that a kind of camping car servo-actuated back axle with following structure is provided: it comprises the back axle permanent seat, turns round axle, hind axle, turn round outer shaft sleeve and a plurality of rubber sleeve gasket; Described back axle permanent seat is connected the bottom of car body bracing frame; Described hind axle with turn round the axle be connected; The described outer shaft sleeve of turning round is connected with the back axle permanent seat; Describedly turn round axle and the rubber sleeve gasket is positioned at and turns round outer shaft sleeve; Described rubber coating cushion cover is being turned round on the axle.
After adopting above structure, the utlity model has following advantage: because the rubber coating spacer that the utility model increases has certain energy-absorbing function, can play buffer action, in other words, rubber sleeve gasket in the utility model can be drawn and turn round the vibratory forces that axle can not in time pass to the car body bracing frame, therefore, turning round axle and can not be subjected to the effect of vibratory forces and phenomenon of rupture takes place in the utility model.
As a kind of improvement of the present utility model, the described axle of turning round can be the solid squares pipe; The described outer shaft sleeve of turning round can be the square hollow pipe; Described rubber sleeve gasket can be have square through hole can rectangular tube; Described turn round axle can with turn round the outer shaft sleeve diagonal angle that can misplace and install.This improvement of the present utility model can strengthen the friction of turning round between axle and the rubber cushion cover, thereby further improves the effect of rubber cushion cover energy-absorbing, because of being subjected to vibratory forces phenomenon of rupture takes place thereby prevent to turn round axle better.
As another kind of improvement the of the present utility model, described hind axle can be connected the torsion rocking arm with turning round between the axle; Described torsion rocking arm and hind axle are with to turn round axle all vertical.Being provided with of torsion rocking arm can increase moment, reduces trailing wheel and passes to the vibratory forces of turning round axle, because of being subjected to vibratory forces phenomenon of rupture takes place thereby prevent to turn round axle better.
