Problems solved by technology

While this helps prevent any contact between the tie rod and the rack and pinion assembly as the tie rod pivots as the wheel travels, the resulting tie rod is relatively short
Having short tie rods can cause jump steer when the wheel travels from its normal resting position
Although the amount of bounce steer is minimal for small amounts of travel, the amount increases with more wheel travel and becomes unacceptable after a certain amount of wheel travel

Embodiment Construction

[0047] The present technology will be described with respect to a four-wheel off-road vehicle 10 having two side-by-side seats and a steering wheel. However, it is contemplated that some aspects of the present technology may be applied to other types of vehicles, such as, but not limited to, off-road vehicles with handlebars and straddle seats (ie, all-terrain vehicles (ATVs)), vehicles with more or less than four wheel off-road vehicles and road vehicles.

[0048] will refer to Figure 1 to Figure 4 General features of the off-road vehicle 10 are described. The vehicle 10 has a frame 12 , two front wheels 14 connected to the front of the frame 12 by a front suspension assembly 16 , and two rear wheels 18 connected to the frame 12 by a rear suspension assembly 20 .

[0049] The frame 12 defines a central cockpit area 22 within which a driver's seat 24 and a passenger's seat 26 are positioned. The frame 12 also defines a roll cage 23 disposed above the cockpit area 22 . In ...

Abstract

A vehicle having a frame; an electric motor; a drive shaft operatively connected to the motor; a front differential operatively connected to the drive shaft; a pair of a pair of front axle shafts; at least one rear wheel; a steering wheel; a steering column operably connected to the steering wheel; a rack and pinion assembly operatively connected to the steering column, the rack and pinion assembly being disposed in the front differential rear; a right tie rod having a left end operatively connected to the rack of the rack and pinion assembly and a right end operatively connected to the right wheel a left tie rod having a right end operatively connected to the rack and a left end operatively connected to the left wheel. The inner ends of the tie rods are arranged in front of a vertically and horizontally extending central plane of the rack.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] For the purposes of the United States of America, this application is of US Patent Application No. 15 / 142,454, filed April 29, 2016, which claims priority to US Provisional Patent Application No. 62 / 155,046, filed April 30, 2015 Continuation application and is a continuation-in-part of US Patent Application No. 15 / 010,773, filed January 29, 2016, which claims priority to US Provisional Patent Application No. 62 / 109,375, filed January 29, 2015. technical field [0003] The present technology relates to a rack and pinion steering system for a vehicle. Background technique [0004] Various types of vehicles exist primarily for off-road conditions. One such type is the side-by-side buggy. The name "side-by-side" refers to the vehicle's seating arrangement in which the driver and passenger sit side by side. Some side-by-side SUVs also have second-row seats to accommodate one or more additional passengers. These vehicles ...
