Abstract

The utility model provides a double-purpose wheel for a motor vehicle to run horizontally or to climb stairs, which is composed of a wheel hub (4), a driving shaft (19), and tyres (7) and is characterized in that the double-purpose wheel is also provided with an anomalous cam (18), an adjusting rod (23), and a sliding pin combined piece which is assembled by a sliding pin (12), a bear pedestal (15), a rolling bearing (17), a compression spring (13), and a shock absorbing head (8); the components form the stairs climbing mechanism of the wheel. After being installed on a light-duty motor vehicle, the double-purpose wheel for the motor vehicle to run horizontally or climb stairs of the utility model can completely realize the purposes of running at a normal speed on the flat ground as well as climbing stairs steadily, can bring great convenience for the user to escape from tiredness; the double-purpose wheel is very applicable to the light-duty motorcycle and the electric wheel riding vehicle.

Description

Horizontal-running and stair-climbing motor vehicle wheel

One, technical field

The utility model belongs to the vehicle wheels that is intended to increase traction, particularly has the horizontal-running and stair-climbing wheel of strap cam stair-climbing mechanism.

Two, background technology

At present, the power actuated vehicle of underload such as motor bike, electric wheelchair, the drive mechanism when travelling on the level land is fairly perfect, but they just can't travel when running into multistage ladder up or down, are with not inconvenience to the motorist; The electric wheelchair cart for travelling up or down stairs of Chu Xianing in recent years, also only being confined to going up or down stairway can be than smooth-ride, and the level land speed per hour very slow (about 420M/h) of travelling, can not be satisfactory to both parties, use same inconvenient.Can keep the normal speed of a motor vehicle to travel on the level land, the dual-purpose wheel of the underload self-propelled vehicle of upper and lower ladder do not seen so far and appeared on the market reposefully again.

Three, summary of the invention

At the above-mentioned defective that prior art exists, propose a kind of horizontal-running and stair-climbing motor vehicle wheel of meter, make it to be installed on the underload self-propelled vehicle and can on the level land, keep the normal speed of a motor vehicle to travel, again can upper and lower reposefully ladder.

Technical solution adopted in the utility model is as follows.

A kind of horizontal-running and stair-climbing motor vehicle wheel includes wheel hub, axle drive shaft and tire, it is characterized in that:

1) its sliding pin assembly set of also having special-shaped cam, adjust bar and being assembled into by sliding pin, bearing seat, antifriction-bearing box, stage clip and damping head is become the stair-climbing mechanism of wheel by these unit architectures;

2) wheel rim of wheel hub is the broadside wheel rim, wheel rim outside fluting mount tyre, and wheel rim inside edge radial equipartition offers lining;

3) with axle drive shaft that wheel hub is captiveed joint on be equipped with successively in cover surface bearing, ball bearing of main shaft and overcoat surface bearing, adjacent face is close to and can be swayed, special-shaped cam and ball bearing of main shaft closely cooperate;

4) sliding pin one end is captiveed joint with bearing seat with stop screw, antifriction-bearing box is bearing on the bearing seat with bearing pin, compression spring sleeve is on sliding pin, the sliding pin other end passes on the wheel rim the uniform lining of offering and captives joint with screw and damping, stage clip one end is against on the bearing seat and the other end is against on the lining outer of wheel rim inwall;

5) adjust bar one end is captiveed joint with special-shaped cam with bolt of rear end plate, and the other end links to each other with vehicle frame, regulates the inclination angle of special-shaped cam by adjust bar.

The horizontal-running and stair-climbing motor vehicle wheel of said structure can also be connected handwheel on the wheel rim of wheel hub with screw and contiguous block, also can rotate handwheel with hand on the level land like this and make vehicle ' and do not need mechanomotive force to order about.

On self-propelled vehicle, adopt the horizontal-running and stair-climbing wheel of the utility model structure, when needs are climbed up ladder, axle drive shaft makes the wheel clockwise direction rotate under dynamic action, the damping head is overhanging can the engagement with ladder under the interlock effect of special-shaped cam and sliding pin assembly set, wheel just smoothly cat ladder (the wheel downstairs is identical reason); Do not need cat ladder and level land when travelling, the effect that the sliding pin assembly set is subjected to stage clip tension force is rolled to minimum radius along the edge greatest radius of special-shaped cam, the radius of damping head is just withdrawn not in contact with the ground less than tire radius, stair-climbing mechanism is just inoperative, wheel travels according to the normal speed of a motor vehicle again on the level land, does not also influence the self-propelled vehicle level land and travels forward or backward.Therefore the horizontal-running and stair-climbing wheel of the utility model structure is installed on the underload self-propelled vehicle and can realizes and can keep the normal speed of a motor vehicle to travel on the level land fully, and the purpose of cat ladder reposefully can be brought great convenience to the user again, avoids fatigue; It is particularly suitable for adopting on by bike at the motor bike of underload and electric drive wheel.
