Description

Novel side wheel bracket rocker arm structure of side tricycle

Technical Field

The utility model relates to a limit wheel bracket rocker arm structure, especially a limit tricycle's limit wheel bracket rocker arm structure.

Background

As shown in fig. 1, a sidecar is generally composed of a motorcycle 2 and a sidecar 1 mounted beside the motorcycle, the sidecar 1 can be seated on, wheels 3 are provided under the sidecar, and the motorcycle 2 can be driven by fuel or by electricity. The side of the side three-wheel on the market is fought at present and is generally direct to be fought lower part installation wheel 3, does not set up the damping structure, has influenced the travelling comfort that the side was fought and has taken and the stability that the whole car was driven. Patent No. CN205075978U patent entitled independent suspension side wheel with three wheels discloses a side bucket wheel supporting structure provided with a damping structure, but because structural design is unreasonable, the structure has many problems such as high requirement on a damping component, easy damage of the damping mechanism, unsatisfactory damping effect, poor side bucket bearing capacity, etc.

SUMMERY OF THE UTILITY MODEL

To the side fill wheel damping spare fragile that exists among the prior art, the damping effect, the poor scheduling problem of side fill bearing, the utility model provides a novel side wheel bracket rocker arm structure of limit tricycle, it has solved among the prior art because of the not good and poor problem of side fill bearing of the not good damping that leads to of structural design unreasonable.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the side wheel bracket rocker arm structure of the side three wheels comprises a shock absorber assembly, a bracket and a rocker arm, wherein the upper end of the shock absorber assembly is connected onto the bracket, the bracket is fixedly arranged on a side bucket body, the lower end of the shock absorber assembly is connected to one end of the rocker arm, the other end of the rocker arm is hinged onto the side bucket body, and a wheel axle is fixedly arranged on the rocker arm.

Further, the bracket is arched, and two ends of the bracket are welded on the side bucket body. The arched structure has good bearing condition, better elasticity and certain vibration reduction effect, and meanwhile, stress distribution is reasonable after stress is applied, and the structure is not easy to damage.

Further, the opening of the arched bracket faces downward in the same direction as the gravity.

Preferably, the bracket is semicircular.

Preferably, the wheel shaft is integrally formed with the rocker arm. The structure can be simplified.

Preferably, the wheel axle surface is plated with copper. The wheel shaft and the wheel hole are generally in over fit or interference fit, and the copper layer is soft and is beneficial to assembly.

Further, the damper assembly is hingedly connected to at least one of the carrier and the rocker arm.

Typically, the damper assembly is a spring damper.

Preferably, the other end of rocking arm articulates on the support, the support welding is in the side fill main part, the oil filler point has been arranged to the normal running fit department of support and rocking arm, the oil filler point is used for to the normal running fit face injection lubricating oil. Lubricated limit wheel bracket rocker arm structure life is longer, and it is better to take the comfort.

Typically, the bracket has a mounting lug disposed thereon. Wheel guards can be installed and otherwise implemented to prevent the rotating wheels from injuring people or hoisting soil to the side buckets.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. the vibration reduction effect is good, and the structure is simple. The form that the rocker arm is suspended by the arched bracket is adopted, the rocker arm plays a role in damping vibration in the action of the vibration damper assembly, and meanwhile, the arched structure is also a vibration damping structure and has a good vibration damping effect.

2. The service life is long. The arched bracket disperses the stress of the wheel, particularly the semicircular bracket disperses the hand force of the wheel to the joint of the bracket and the side bucket to be the vertical force, the stress condition is not easy to damage the vulnerable parts such as the welding part, the whole service life is longer, and the vertically arranged shock absorber assembly can better play the shock absorbing effect.

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

As shown in fig. 1-5, the utility model provides a side wheel bracket rocker arm structure of limit tricycle, including shock absorber subassembly 16, bracket 15 and rocking arm 14, the upper end of shock absorber subassembly 16 is connected on bracket 15, bracket 15 is the arch, and the both ends welding of bracket 15 is on limit fill main part 11. The opening of the arched bracket 15 is downward in the same direction as the gravity, and the bracket 15 may be semicircular. The lower extreme of shock absorber subassembly 16 is connected in the one end of rocking arm 14, and the other end of rocking arm 14 articulates on support 12, and support 12 welds on sidecar body 11, and oil filler point 13 has been arranged to the normal running fit department of support 12 and rocking arm 14, and oil filler point 13 is used for pouring into lubricating oil to the normal running fit face. The rocker arm can also take the form shown in figure 5, with the end provided in the form of a sleeve provided with an oil orifice 13 hinged to the support 12 by a pivot pin. The rocker arm 14 is fixedly provided with a wheel shaft 141, the wheel shaft 141 and the rocker arm 14 are integrally formed, and the surface of the wheel shaft 141 is plated with copper. The shock absorber assembly 16 is hingedly connected to at least one of the carrier 15 and the rocker arm 14. The damper assembly 16 is preferably a spring damper.
