Abstract
A kind of power of pedaling racing car of the usefulness that is suitable for racing, it comprises front-wheel and trailing wheel, handlebar, front fork tube and vehicle frame, the top that prostrate having takeed on the body holder that keeps off and be positioned at vehicle frame that is suitable for as the human support organization, the pedal assembly is positioned at the rear portion of vehicle frame, make it to be in the back upper place of trailing wheel, its force angle is greater than 150 °.This pedals power racing car is a kind ofly to pedal and use the vehicle for counter-force, and to change striding type be prone type, and more original foot-operated racing car speed is fast.
Description
The invention belongs to a kind of vehicle, specifically, relate to a kind of strength of one's legs racing car of the usefulness that is suitable for racing for land use.
In the prior art, general donor is educated the strength of one's legs racing car that contest uses and is the foot-operated racing car of striding type.The foot-operated racing car of this striding type generally is made of wheel, vehicle frame, handlebar, saddle and foot-operated assembly and chain etc., and its principal feature is positioned at the below, seat for foot-operated assembly, the posture supporting health of treadmill people this moment to ride.Because this posture is by perineal position groove supporting weight under the pelvis, serious when riding to the friction of perineum place, as racing car the time, will influence the performance of sportsman's muscle power.Simultaneously, (human body line of centers and foot-operated assembly center respectively and the angle between the line of hipbone) is less than 150 ° because the force angle of the foot-operated racing car of this striding type, so legpower is the upper limit with treadmill people's body weight, thereby make the sportsman can not bring into play potential muscle power to improve the speed of a motor vehicle.In addition, the people of this class racing car, the common center of gravity of car are higher, the stability that influence is travelled and to make human body be subjected to resistance bigger, and this also can influence the further raising of speed.
The purpose of this invention is to provide a kind of speed faster, the power of the pedaling racing car of the usefulness that is more suitable for racing.
In order to achieve the above object, the present invention has done following improvement to existing foot-operated racing car: the original saddle as the human support organization is changed into be suitable for the prostrate body holder that is positioned at the vehicle frame top, this body is entrusted the shoulder retaining of the support reaction that can bear the power of pedaling that racing car provides human body; Change foot-operated assembly into back upper place that rear portion that pedal Zong Cheng And is positioned at vehicle frame makes it to be in trailing wheel, this pedal assembly links trailing wheel with it by chain and sour jujube formula gear wheel; The force angle of this pedal racing car is greater than 150 °.
In order to cooperate above-mentioned improvement, the vehicle frame of this pedal racing car and handlebar also need be done corresponding change, this change can be a various ways, as a kind of example, vehicle frame and handlebar can adopt following form: vehicle frame is made of preceding straight tube and Vee formation pipe two parts, the front end of preceding straight tube adopts surface bearing mechanism to link to each other with the upper end of front fork tube, and above-mentioned pedal assembly is loaded on the joint of pedaling of Vee formation pipe rear end, and trailing wheel and sour jujube formula gear wheel are loaded on the rear wheel fork place of Vee formation pipe lower end.
Advantage of the present invention is tangible, because the structure of racing car has been done above-mentioned change, just change the foot-operated system of original striding type into prone type pedal system, and because the rider has an effect with prone position, force angle is greater than 150 °, so pedaling power is not the upper limit with the body weight, shoulder retaining and handlebar are simultaneously to rider's human body effect, for the rider provides support reaction, rider's whole-body muscle is participated in simultaneously to be had an effect, site distribution is wide, power is big, endurance is good so have an effect, and so just can give full play to rider's muscle power, accelerates the moving velocity of racing car.Secondly, rider's center of gravity is lower, is example with wheel footpath 26 inch, and the gravity center of human body highly is about 74 centimetres, and the common center of gravity of people, car is also low, so the riding stability of this racing car is good; Simultaneously, the gravity center of human body is after the subpoint on the ground supporting line is also ridden racing car partially than striding type, and the trailing wheel upward pressure as driving wheel increases like this, and friction force also increases especially, impels the improvement of acceleration, driving and deceleration performance.Once more, the rider gets front lying position, longitudinal projection's area little (cross section that promptly facings the wind is little), and resistance of motion also just reduces; The appearance of bowing of human body upper body be by after go up forward tiltedly, like this rider's back neck do not resemble use the foot-operated racing car of striding type nervous, because the body support is long-pending big, bent body compressing chest belly, so rider's oxygen debt problem is little, flesh can be saved, the muscle power high efficiency, and since this racing car with the human bearing position with pedal power support reaction bearing position and separate, by position supporting weights such as the stern that is suitable for load-bearing, waist, the back ofs the body, because of the body support is long-pending bigger, can alleviate the pressure at supporting position like this, reduce the friction force between human body and the body holder.
Provide one embodiment of the present of invention below in conjunction with accompanying drawing,, will make details of the present invention and advantage more obvious by specific descriptions to this embodiment.
The drawing explanation of accompanying drawing:
The structural representation of the embodiment of Fig. 1, prone pedal race bicycle.
Referring to Fig. 1, the structure of present embodiment is as follows: it has two front vehicle wheel (6) and rear wheels (9) that diameter is identical, a front fork tube (4) and a vehicle frame (8), the front portion of this vehicle frame (8) is a preceding straight tube (8a), the rear portion of vehicle frame (8) is a Vee formation pipe (8b), constitute captive joint with a three-way pipe (8c) between preceding straight tube (8a) and the Vee formation pipe (8b), there is a surface bearing mechanism (2) the front end below of preceding straight tube (8a), this surface bearing mechanism (2) is rotationally connected vehicle frame (8) and front fork tube (4) formation, there is a front wheel spindle (5) lower end of front fork tube (4), front-wheel (6) is installed on the front wheel spindle, handlebar (3) direct mount stretches out to oblique the place ahead in front fork tube (4) Shang Bu And, has the mechanism of control brake on this handlebar (3).The support tube (1b) that the body holder (1) of one supporting strap shoulder retaining is arranged in the front portion of preceding straight tube (8a), the front portion of body holder (1) extends upward part and is shoulder retaining (1a), the horizontal component (1b) of body holder (1) is made the shape that adapts with the human body front portion, body holder (1) can be made by sponge or other elastic flexible material, front and rear in body holder (1) respectively has a pressure spring (17a) to link to each other with preceding straight tube (8a) with (17b), rear wheel fork (8d) the Shang ， And that sour jujube formula gear wheel (10) is installed on the lower end of Vee formation pipe (8b) links to each other with trailing wheel (9).Pedal assembly (14) be installed on Vee formation pipe (8b) the rear end pedal joint (8e), at the other change wheel (12) of installing again of sour jujube formula gear wheel (10).Chain (15) is on big gear wheel (14a), sour jujube formula gear wheel (10) and the change wheel (12) of pedal assembly (14), make it to constitute interaction relation, can drive trailing wheel (9) rotation in the time of on pedaling with the step tread plate (14b) of human pedal pedal assembly (14), And regulates the speed of a motor vehicle by change wheel (12).The spike (11) of downward extension also is housed in the lower end of Vee formation pipe (8b), supports the usefulness of car body during for parking.
