TH42306B - Foot brake structure of scooter vehicles - Google Patents

Abstract

In the DC60, to reduce the size of the foot brake structure and increase the autonomy of the design, thereby reducing the number of man-hours for machine building and lowering the cost of the foot brake structure, in the scooter-type foot brake structure, a pair of left and right footrests 31, supported by the main frame 18, is arranged between the steering handles and the two-part seat. The brake pedal 33, for controlling the rear wheel braking device, is rotatably attached to the main frame 18, and the tread portion 33b of the brake pedal 33 extends over the footrest 31, with the footrest 31 supported by support bracket 81, a component of the chassis 11. The pivot point 34 for the brake pedal 33 is provided on support bracket 81, and the pivot point 34 is arranged above the main frame 18 and under the footrest 31 when viewed from the side.

Claims (5)

1. The foot brake structure of a scooter vehicle in which a pair of left and right footwells (31), supported by the chassis (11), are provided between the steering handle (16) and the seat (66); the brake pedal (33) for controlling the braking device (32) for braking the wheels (23) is rotatably attached to the chassis (11), and the tread (33b) of the brake pedal (81) extends over the footwells (31), where: the footwells (31) are supported by a support bracket (81) provided on the chassis (11), the pivot (34) for the brake pedal (33) is provided on the support bracket (81), and the pivot (34) is provided on the chassis (11) and under the footwells (31) when viewed from the side; the support bracket (81) extends as a single piece along the length of the footwells (31) and the locking trajectory. To maintain the brake pedal in the specified pressed position during the lowering of the brake pedal (33) is ensured by the support bracket (81); the brake pedal (33) includes the main arm (33a) which extends forward from the pivot side (34) and the connecting arm (33a) which extends backward and downward diagonally from the pivot side (34) and (34), the support bracket (81) supports the connecting arm (86) which forms the locking mechanism at the rear position of the brake pedal (33); and the connecting arm (86) has an end supported by the support bracket (81) to allow it to swing forward-backward and is connected to the brake pedal (33) interface to maintain the brake pedal (33) in the specified pressed position. 2. The foot brake structure of a scooter vehicle under claim 1, where: the support bracket has a U-shaped cross-section with an opening facing downwards; the rear of the support bracket is mounted on the chassis; and the pivot shaft is inserted through the transverse support bracket and is fixed on both transverse sides of the support bracket. 3. The foot brake structure of a scooter vehicle as per claim 1 or 2, where the connection point between the brake pedal and the pivot is arranged on the outer transverse side of the chassis when viewed from above. 4. The foot brake structure of a scooter vehicle under any of the claims 1 through 3, where: the support bracket extends in a continuous, longitudinal direction along the footrest; the locking mechanism for maintaining the brake pedal in the specified down position at the time of pedal press and the cable for connecting the control unit for controlling the locking mechanism to the locking mechanism are supported by mounting brackets mounted on the support brackets respectively; and the mounting brackets are provided before and after the pivot point. 5. The foot brake structure of a scooter vehicle under any of the claims 1 through 4 shall be such that: the cable assembly consists of an outer and an inner cable which is movably inserted into the outer cable; the mounting bracket for supporting the cable shall have the end of the outer cable fixed to the bracket in a fastening manner and be made into an L-shape so that the outer and rear transverse sides of the cable end are covered when the vehicle is viewed from above; and the holes through which the fastening manner is visible are provided at the angle of the L-shape.
