Problems solved by technology

This invention has two major defects: one is that the brake is installed asymmetrically, but is positioned by the frame and the rear axle, so a large and heavy frame frame is required to install the rear axle, otherwise the brake cannot be installed; The second is that there is no synchronization device installed between the left and right brake arms and the brake, but a rigid connection with a tie rod, which can easily lead to uneven force on the brakes on both sides, so there is still the possibility of vehicle deviation or rollover
Although this solution can achieve dual rear wheel brakes, it is not "light". The installation of the differential makes the structure of the rear axle complex, which greatly increases the weight and processing costs of the vehicle, and makes it difficult to drive manually.

Embodiment 1

[0048] Embodiment one: the present embodiment is a portable tricycle that adopts double rear wheel brakes. As shown in Figure 5, the main frame 1 of this tricycle adopts the ordinary bicycle frame, and its flat fork 41 and vertical fork 44 also adopt the flat fork and vertical fork of ordinary bicycles (because the opening of the left and right fork pipes is small, it is called It is a small flat fork and a small vertical fork), and the difference is that the joints on both sides of the rear end of the flat fork 41 are improved. The improved flat fork joints 42 and 42 are semi-elliptical sheets (rectangular sheets are also acceptable), made of metal plates with a thickness of 3mm, and are provided with 3 assembly grooves opening downwards, wherein the assembly grooves on both sides The groove is used to install the two transverse connecting pipes 32, 32 described below, and the assembly groove in the middle is clearance fit with the rear axle 9, so that the rear axle 9 can run...

Embodiment 2

[0052] Embodiment two: as shown in Figure 8, the present embodiment is a portable four-wheel vehicle that adopts double rear wheel brakes. The brake 2 in the braking device adopts a common bicycle brake, and the composition of the brake 2 and the connecting piece assembly 3 and its connection method, and the connection method between the brake 2 and the connecting piece assembly 3 are the same as those in the embodiment. The link assembly 3 is installed on the rear portion of the main frame 1 through the positioning connector 4. The positioning connector 4 includes a guide plate 45 and shock absorbers 46, 46. The front end of the guide plate 45 is hinged with the main frame 1, and its rear end It is fixedly connected with the transverse connecting pipes 32, 32 in the connecting plate assembly 3, and elastically connected with the main frame 1 through shock absorbers 46, 46.

Abstract

The present invention relates to a two-wheel brake device of light tricycle and four-wheel car. Said brake device is characterized by that one of band brave, expanding brake or dish brake of bicycle is selected, and can be left and right symmetrically mounted on the outside of connecting strap assembly, and placed on same axis with spring of connecting strap assembly. Said connecting strap assembly includes left and right connecting straps, transverse connecting pipe whose two ends are connected with left and right connecting straps and spring mounted between said connecting straps. Its structure is simple and brake is reliable.

Description

【Technical field】 [0001] The invention relates to a brake device and a vehicle using the device, in particular to a two-wheel brake device and a light tricycle or four-wheel vehicle using the brake device. 【technical background】 [0002] The rear wheel braking device of an ordinary tricycle is generally installed in the middle of the rear axle, and only acts on the fixed wheel on one side during braking. Although some tricycles have rim brakes installed on the two rear wheels, the braking point is only on one side of the rim, the friction surface is small, the braking effect is not ideal, and it causes excessive wear on one side of the rim; And radial deformation, poor contact between the brake skin and the rim during braking will also greatly reduce the braking effect. ZL 03241007.7 discloses a brake device for movable wheels of a tricycle, which realizes the braking of double rear wheels. The structure of the device is complicated. ZL 02275492.X is the closest compariso...
