TH20293B - Front wheel steering device for motorcycles and tricycles - Google Patents

Abstract

The DC60 (30/08/43) front wheel steering gear for motorcycles (10) and trike will be provided where Kingpin's center (P2) (53) and center (P1) of Steering axles (73) are located opposite from each other. And the joint (85), the connection between the first link (82) and the second link (84), which makes up the link (80), will be a soft joint (86). Soft coupling (86) absorbs the positional deviation of the steering shaft (73), which occurs when the vehicle chassis shape and dimensions (11A) are changed. Therefore, if the vehicle chassis shape and dimensions (11A) are to be changed then the swing arm (52) and the link mechanism (80) will not need to be changed and can be used together. The front wheel steering device for motorcycles (10) and tricycles will be provided where the Kingpin center line (P2) (53) and center line (P1) of the steering axle (73) are located. Indent from each other And the joint (85), the connection between the first link (82) and the second link (84), which makes up the link (80), will be a soft joint (86). Soft coupling (86) absorbs the positional deviation of the steering shaft (73), which occurs when the vehicle chassis shape and dimensions (11A) are changed. Therefore, if the vehicle chassis shape and dimensions (11A) are to be changed then the swing arm (52) and the link mechanism (80) will not need to be changed and can be used together.

Claims (3)

1. Front wheel steering device for front wheel steering (18) of one of Motorcycles and tricycles, the device contains: Main frame (11); Swing arm (52) fixed in a vertically swaying position to the main frame; The axle holding block (54), fixed horizontally, is attached to the swing arm through the kingpin; (53) Front wheels (18) fixed in such a way as to be fixed to the said axle mounting block; (54) Hinge joint (57) Extending from the clamping block The axle, (54) and the link mechanism (80) connected to the steering axle (73) are attached. Another rotatable end is with the header tube (72), with one end connected to the aforementioned hinge joint (57) and the opposite end arranged in a unified manner to the main frame. Said, which makes it unique is The aforementioned kingpin (53) has a misalignment compared to the center of the steering shaft. Such a turn (73) and is positioned so that it does not pass through the center of the front wheel (18); And the link mechanism (80) consists of a bendable link piece with one link piece (82) and a second link piece (84) connected together at one of the joints. The piece is linked through the soft coupling (86) so that the first and second linking pieces are Will be able to bend around Such a coupling for admission to the vertical movement of the said front wheels. 2. Front wheel steering device according to claim 1, where the aforementioned flexible coupling (86) is assembled with a ball joint. 3. One of the front-wheel steering devices according to claim 1 or 2, where the header tube (272) has the top plate (274) and the bottom plate (277) located in Replaceable characteristics Located at the top and bottom of the header tube, the top plate and the bottom plate thereof. Each plate has a through hole for the steering shaft (273) through the said hole so that the centerline of the steering shaft intersects with the centerline of the header pipe. Such is a given angle.
