Abstract

The utility model discloses a wheel casing capable of braking, which comprises a casing shell fixed on a wheel carrier. The utility model is characterized in that the casing shell is movably connected with the wheel carrier through a pin shaft, and the wheel carrier is also fixed with springs which are used for supporting the casing shell; the inner surface of the casing shell is also provided with a plurality of convex teeth. The wheel casing can be used on various vehicles, and therefore, brakes can be conveniently carried out by means of feet treading on the wheel casing; especially when the wheel casing is used on a pedal vehicle, the mechanism of the pedal vehicle is simplified, and the operation of the pedal vehicle is convenient.

Description

The wheel cover that can brake

The utility model relates to a kind of wheel cover that brakes.

The almost various vehicles of wheel cover all have, and its function ratio of general wheel cover is more single, only in order to cover on the mud in order to obstruct the road and upward to splash owing to wheel turns on the wheel.

The purpose of this utility model is to propose a kind of wheel cover that brakes, and it both can play the wheel cover effect, can use as braking mechanism again.

The purpose of this utility model is to realize like this, a kind of wheel cover that brakes, it includes the case that is fixed on the wheel carrier, described case forms rotatable the connection by a bearing pin and wheel carrier, also be fixed with on wheel carrier in order to hold the spring of case, its inside face of described case also is provided with several double wedges; Described in order to the spring of holding case can for one be fixed on the wheel carrier and with the contacted spring leaf of case inside face.

The wheel cover that the utility model can brake, the way of the case that can tramp with one's feet is braked, and is simple and direct, reliable, and optimum is installed on the scooter rear wheel frame.

Below in conjunction with drawings and Examples the wheel cover that the utility model can brake is described in further detail.

Fig. 1 is that the master of the utility model wheel cover band semi-sictional view that can brake looks scheme drawing.

Fig. 2 is the A-A cross-sectional schematic of Fig. 1.

Fig. 3 is the B-B cross-sectional schematic of Fig. 1.

To be that case is stressed among Fig. 1 move down Fig. 4, and wheel is in the scheme drawing of braking state.

Fig. 5 is that wheel cover that the utility model can brake is installed in the situation on the scooter rear wheel frame.

Referring to Fig. 1, Fig. 2, Fig. 3, wheel (6) is fixed on the wheel carrier (3) by minor axis (8), also be fixed with case (1) on the wheel carrier (3), this case (1) is fixed on the wheel carrier (3) with a bearing pin (2), by this bearing pin (2), case (1) forms rotatable the connection with wheel carrier (3), on wheel carrier (3), must be fixed with the spring that to hold case (1), the most simple and reliable way is the spring leaf (5) that bends to approximate S shape with, the one end is fixed on the below of wheel carrier (3) with screw (7), the other end is held case (1), case (1) can not contact with wheel (6) when stressed like this, wheel (6) is free to rotate, case (1) can be cast with several length differences in the surface within it with aluminium alloy casting, the double wedge of Fen Buing (4) in length and breadth, this double wedge (4) can be granular, banded or block its radial section can be triangle or quadrangle and other shapes, wheel (6) has rubber outer, when can the extrude rubber outer of wheel (6) of when brake double wedge (4), the rotation of wheel (6) is played shock damping action.

Referring to Fig. 4, when needs brake, firmly step on case (1) with pin, represent direction firmly with the arrow of F mark among the figure, case (1) just is adjacent to wheel (6) skin, the rubber outer of case (1) double wedge (4) that inside face distributed extrusion wheel (6) forces wheel (6) to stop operating and has just played braking action, after the power on the case (1) of being added in is cancelled, case (1) is because the elastic force of spring leaf (5) lifts again and sets back, and the inside face of case (1) and wheel (6) disengage the brake action that has also just stopped wheel (6).

Referring to Fig. 5, it is very suitable that the utility model is installed on the wheel carrier (3) at scooter rear portion, when scooter travels with very fast speed, meets the situation that needs emergency brake, the driver just can realize rapidly braking and guarantee safety as long as step down on the case (1) of rear wheels (6) with pin.

Claims

1. wheel cover that can brake, it includes the case (1) that is fixed on the wheel carrier (3), it is characterized in that: described case (1) forms rotatable the connection by a bearing pin (2) and wheel carrier (3), also be fixed with on wheel carrier (3) in order to hold the spring of case (1), its inside face of described case (1) also is provided with several double wedges (4).

2. the wheel cover that brakes according to claim 1 is characterized in that: described in order to the spring of holding case (1) be one be fixed on that wheel carrier (3) is gone up and with the contacted spring leaf of case (1) inside face (5).
