a wheel type steering device comprises a steering wheel, a power-assisted steering column, a first gear, a second gear, a front fork, wheels, a transmission shaft, a shock absorber and a gear fixing seat; the two ends of the power-assisted steering column are respectively connected with a steering wheel and one end of a transmission shaft, the two ends of a gear fixing seat are respectively connected with the other end of the transmission shaft and a first gear, the first gear is meshed with a second gear, the front fork comprises a front fork body and a connecting platform which is welded with the top of the front fork body into a whole, the second gear is fixedly arranged on the connecting platform, connecting swing arms are respectively arranged on the two connecting ends of the front fork, and the connecting swing arms are connected with wheels through shafts; the both ends of bumper shock absorber respectively with connection platform and connection swing arm fixed connection.

Through being connected the bumper shock absorber with connection platform and swing arm respectively, replaced original directness and front fork direct design structure as an organic whole, when the road surface is uneven or road surface both sides are not at same height like this, the bumper shock absorber on both sides can exert absorbing effect in step, compares integrative structure, can avoid both sides relative motion, reduces the problem that rocks about the vehicle. In addition to this, comfort is better under different loads.

Specifically, the diameter of the first gear is smaller than the diameter of the second gear. The pinion gear can reduce the steering force and reduce the occupied space, and at the same time, can achieve the effect of transmission.

Specifically, a fixed sleeve is arranged in the center of the connecting swing arm, and the fixed sleeve is rotatably connected with a bearing of a wheel through a wheel shaft.

Specifically, the ratio of the moment arm of the wheel to the moment arm of the shock absorber is 2:5, so that the bearing capacity of the shock absorber can be increased.

To sum up, the utility model discloses the device has following advantage: the device realizes improving the bearing capacity of wheel, reduces the swing when improving the comfort, promotes the shock attenuation effect.

Detailed Description

The present invention will be further explained with reference to fig. 1.

A wheel type steering device comprises a steering wheel 1, a power-assisted steering column 2, a first gear 4, a second gear 10, a front fork 9, wheels 5, a transmission shaft 3, a shock absorber 6 and a gear fixing seat 11; two ends of the power-assisted steering column 2 are respectively connected with one end of the steering wheel 1 and one end of the transmission shaft 3. In order to improve the transmission precision and the transmission efficiency, gear transmission is adopted between the transmission shaft 3 and the wheels 5. The key groove of the first gear 4 is connected with the gear fixing seat 11, and then the other end of the transmission shaft 3 is connected with the gear fixing seat 11, so that the transmission connection between the transmission shaft 3 and the first gear 4 is realized. Then, the first gear 4 is meshed with the second gear 10, and the diameter of the first gear 4 is smaller than that of the second gear 10, so that the first gear 4 is smaller, the steering force is reduced, the occupied space is reduced, and the gear transmission effect can be realized. Front fork 9 includes the front fork body and welds connecting platform 12 on the front fork body top, and second gear 10 fixed mounting is on connecting platform 12, in order to increase the load bearing capacity, and the travelling comfort is better under different loads, so be equipped with respectively on two joints of front fork 9 and connect swing arm 8, be equipped with fixed cover in the center of connecting swing arm 8, fixed cover passes through axletree rotatable coupling with the bearing of wheel 5. The two ends of the shock absorber are respectively and fixedly connected with the connecting platform 12 and the connecting swing arm 8, and the ratio of the moment arm of the wheel 5 to the moment arm of the shock absorber is 2:5, so that the bearing capacity of the shock absorber can be increased. Through being connected the bumper shock absorber respectively with connection platform 12 and connection swing arm, replaced original directness and front fork 9 direct design structure as an organic whole, when the road surface is uneven or road surface both sides are not at same height like this, the bumper shock absorber on both sides can exert absorbing effect in step, compares integrative structure, can avoid both sides relative motion, reduces the problem that rocks about the vehicle. In addition to this, comfort is better under different loads.

The use process of the device is as follows: when the steering wheel 1 rotates, the electric power-assisted pipe column receives a signal to start the power-assisted motor to work so as to provide power assistance. The power is transmitted to the first gear 4 through the transmission shaft 3, and the first gear 4 drives the second gear 10 to rotate, so that the front fork 9 is driven to rotate. The wheel 5 is connected with the connecting swing arm 8 through a wheel shaft, the ratio of the wheel to the force arm of the shock absorber is 2/5, and the bearing capacity is increased. When the road surface is uneven, the two swing arms swing up and down synchronously, so that the vehicle is prevented from shaking left and right.

As can be seen from the above description, the device has the following advantages:

the device can improve the bearing capacity of wheel, bumper shock absorber synchronous motion, and both ends are connected with swing arm and connection platform 12 respectively, reduce the swing when can improve the comfort like this, promote the shock attenuation effect. The device can also be used in a sweeper, and the device can also keep the disc brush and the suction port at a stable ground clearance to better protect a sweeping system.

It should be understood that the above detailed description of the present invention is only for illustrative purposes and is not limited to the technical solutions described in the embodiments of the present invention. It will be understood by those skilled in the art that the present invention may be modified and equivalents may be substituted to achieve the same technical effects; as long as the use requirement is satisfied, the utility model is within the protection scope.
