Abstract
The utility model relates to a tricycle steering mechanism. The tricycle steering mechanism is characterized in that: the left and right front wheels are respectively provided with a brake mechanism and a differential mechanism, both ends of the differential mechanism are respectively connected with the driving shaft and also provided with an operating lever, a control lever and a rotator, the left and right operating levers are respectively arranged on the tricycle frame and the lower part of the operating lever and the control lever are connected and fixed by the screw bolt, and the other end of the control lever and the rotator are fixed and connected by the screw bolt and the rotator is arranged on the top of the fork joint of the caster. When the rotator is in locking condition, the left and right operating levers are driven to make the caster steer, and the purpose of steering is achieved. When the rotator is in free condition, the purpose of steering is achieved by using the cooperation of the brake assembly and the differential mechanism. When the tricycle is braked by the single brake disk, the differential mechanism conveys different force moments to the two front wheels and the rotation speed of one wheel becomes slow, and then the tricycle rotates or turns because of the different rotation speeds of the two front wheels.
Description
Technical field
The utility model relates to a kind of three-wheel vehicle, especially relates to a kind of three-wheel vehicle steering hardware.
Background technology
At present, the three-wheel vehicle structure comprises two rear wheels and a preceding steering wheel, use two geared wheel to push ahead by geared wheel and ground friction, the travel direction of vehicle is to be realized by the guide of front-wheel and control, this structure only is suitable for carriage for children and low speed car, if three-wheel vehicle speed is accelerated suddenly or wheel is too fast, must turn in travelling or steering procedure in, three-wheel vehicle travels and will become unstable.For example: US Patent 4826190 has been put down in writing by prolonging and reducing the technical scheme that vehicle frame improves the stability of vehicle, and still, radius of rotation has been sacrificed in this design, and requires bigger operational space; US Patent 4925202 is by changing the assembling of wheel, only use one in two front-wheels to travel, another front-wheel is used for braking, and trailing wheel is as steering wheel, the operation though this assembling is more convenient for, front-wheel is in the stability that has limited vehicle aspect braking and travelling; US Patent 5071150 attempts improving this operability, yet this set must increase extra weight to vehicle---and with the form of weight device, make front-wheel break away from ground, thereby vehicle is rotated on the pivot by rear braking wheel in short device; US Patent 4484646 provides a very low center of gravity, and is more easy to operate, but its driving device is only just effective when being connected with motor.
Learn after the Chinese patent application by retrieval: the patent of relevant three-wheel vehicle has part in the Chinese patent application, and wherein patent of invention has 152, and utility model patent has 1891, and design patent has 8, and the patent that relates to control three-wheel vehicle steering hardware has 4.
For example Chinese patent 02216284.4 relates to a kind of back pushing handle type three-wheel vehicle steering hardware, comprise: turn to push rod, steering track rod, the car after-frame, it is characterized in that: also comprise a steering hardware, this steering hardware is fixed by stationary pipes and car after-frame, stationary pipes built-in one is rotated inner core, respectively establish on one therebetween, following bowl, on, following bowl is built-in with a plurality of steel balls, be stamped on the steel ball, following retaining rotates the top of inner core and establishes a position-arresting ring, and a connecting piece is put in its lower end, and fix with locking cap, connecting strap links to each other with steering track rod, turns to push rod to place and rotates interior in-core, is fixed by the chuck of its upper end.
There is not the patent application of record and the same or similar technical scheme of the utility model patent application in the Chinese patent application.
Summary of the invention
