Abstract
A pedal powered vehicle with at least one front wheel 5, and two rear wheels 13,17, which are mounted by pivot arms 11,23 to a frame 1,24, wherein the pivot arms 11,23 are mounted coaxially with the axis 22 of a driving pedal crank by means of a bearing on the frame 24. The pivot arms 11,23 have an inner cavity which contains a driving wheel (34, figure 4), a driven wheel (33 figure 4), and an endless tension element (32, figure 4) for transmitting driving force from the driving wheel 34 to the driven wheel 33. An electric motor (39, figure 4), battery pack (31, figure 4) and controller (30, figure 4) may also be included. A shock absorber provides suspension and allows limited tilting of the cycle.
Description
Current common three-and four-wheeled bicycles and other vehicles have fixed connected axis (tandcm axis), which does not permit any tilting. This makes turning very difficult. Those trikes! tricycles have a static middle axis where the chain or belt is connected with the back wheels as well as with the pedals.
There are few examples where tilting mechanisms are used. However, in those cases in which tilting mechanisms are used, there is the problem that the pivot of tilting is not connected with the pedal axis, which makes pedalling difficult, because they need an additional chain tensioner or belt tensioner so that the chain always remains tense without dislodging. The tensioner significantly reduces the efficiency of pedalling power. Moreover, chain! belt tensioners do not permit enclosed chains, which results in the additional burden of high maintenance, dirty chains and regular dislodging of the chain.
The present invention seeks to provide a solution to all of the above-mentioned drawbacks of current tilting and not tilting bikes by providing three-and four-wheeled bicycles and other vehicles with a mechanism that makes it possible to reduce the traction of a chain, belt, or rim connected to one or more tilting wheels powered by pedal and/or motor driven vehicles.
A preferred embodiment of the invention will now be described with reference to the accompanying drawings in which: Figure 1 shows a perspective view of a three-wheeled vehicle, comprising a main frame middle bar (i), containing a middle frame main axis mount (24), containing a middle frame main axis (22), connecting to movable, or fixed load storage arm/bar (3), attached to a load storage platform (6), including a quick release mechanism to mount and dismount cargo box or other devices from the platform (25), including an extendable load storage platform part (15). A three-wheeled vehicle comprising back wheels, one of which (13), containing a back wheel axis (20), attached to a back wheel movable arm/ bar (11), connecting middle frame main axis (22), connecting middle frame main axis mount (24). A three-wheeled vehicle comprising back wheels, one of which(1 7), containing back wheel axis (21), attached to movable back wheel ann bar (23), connecting middle frame main axis (22), connecting middle frame main axis mount (24). The three-wheeled vehicle comprising a right pedal (12), attached to the middle frame main axis (22), connecting a back wheel movable arm! bar (11), connecting middle frame main axis mount (24), connecting a back wheel movable arm! bar (23) attached to the left pedal (8). A three-wheeled vehicle comprising movable variable support suspension element (18), connecting a back wheel movabk arm! bar (11), connecting a movable back wheel arm! bar (23), connecting the load storage arm/bar (3) and! or main frame middle bar (1). A three-wheeled vehicle comprising seatpost (7), including seat (10) connecting the main frame middle bar (1). A three-wheeled vehicle comprising front steering bar (19), connecting stem (2), connecting the mainframe middle bar (1), connecting front wheel fork (16), connecting front wheel (5).A three-wheeled vehiclc may be a pedal-assisted, motor-assisted tricycle driven with or without human power. When ridden it may tilt to the left and to the right, which makes it easy for the rider to steer and turn left or right. The three-wheeler is more stable to ride when loaded with additional weight! cargo. The movable arm! bar (11) and back-wheel movable arml bar (23) grants this flexible movement in the curves. The load storage platform (6) may allow the user to load and fix cargo and to place additional items like children's seats, or a cargo box (40). the quick release mechanism helps to mount and dismount cargo from the platform (25).
Each one of the two back wheel movable arms! bars (11) and (23) may include a motor (39), it may include a power source for the motor (31); ft may include an electronic control circuit board (30); it may include a gear box (14); it may include at least one small transmission wheel (33); it may include at least one chain, rim, belt, etc. (32); it may include at least one big transmission wheel (34). The middle frame main axis mount (24) connects each one of the two back wheels movable arms! bars (11) and (23) and the main frame middle bar (1). The connection may be flexible and this may allow the vehicle to tilt to the left and to the right while using the pedals (12) and (8). They are connected with the middle frame main axis (22) containing at least one big transmission wheel (34), allowing the user to pedal and to move the enclosed chain, rim, belt, etc. (32); allowing to transmit the movement to at least one small transmission wheel (33); and the gear box (14), connecting the back wheel axis (21), or (20), and making the back wheel (17), or (13) rotate. This allows the riding and driving of the three-wheeled vehicle as well as tilting at the same time in curves. The movable variable support suspension element (18) may be used as a suspension, or/and at the same time holds together and sets limits on the degree of tilting and pedalling. It may as well be used as a connecting clement of all back wheel movable arms! bars (11) and (23), movable, or fixed load storage ann/bar (3) and, or main frame middle bar (1). This element may be made out of rubber, metal, plastic, etc. The preferred material is rubber and metal, most preferred material is rubber.
